स्फुटचन्द्राप्त • • • The Sphutacandrapti of Madhava, edited here for the first time from its only known manuscript, enun- ciates an easy and ingeni- ous method which would enable the accurate com- putation of the the Moon at intervals of about 40 minutes each throughout the day. The Chart pre- pared for the above pur- pose is so designed that, with minor changes, it could be used for several days in succession. The author, MSdhava of Sahgamagrama, is an astute astronomer of medi- aeval Kerala (c. 1340-1425), who has several works to his credit. He is widely quoted by later astonomers of Kerala and is also reputed for his enunciation of formulae for the accu- rate determination of the circumference of a circle and the nature of 7T by the method of .indetermin ate series, a method which was re-discovered in Europe about three centu- ries later by James Gregory (1638-75) and Wiihelm Leibnitz (1646-1716).

A.D. 1340-1425), critically edited here for the first t111e , enunciates an ingenious method for the computation of the True Moon. Besides being the fastest graha, the Moon has also the maximum changes in its motion, with the result that its p0sition if calculated on the basis of its position at sumrise and/or at Sunset and its average motion for the day would give only rough results. Madhava describes in the present work the construction of a Chart from which the True M001 could be read out at intervals of about 40 minutes each throughout the day. The Chart is also so designed that, with minor changes, it could be used for the succeeding days as well The critical edition of Spl11410c07drapti, presented in the following pages , is based on its only available manuscript. For facilitating the comprehension of this technical treatise, an English rendering has been added on pages facing the text. In the foot 10tes to the edition, an endeavour has been made to derive the several formulae enunciated by the author for the computation . The principles underlying the method have been set out in detail in the Introduction that follows this Preface. A concrete example has also For ensuring accuracy in the above, it is essential that the daily motion of the Moon used for the calculations is very accurate. The Moon-sentences of Vararuci, which are ordinarily used in Kerala astronomical practice, 1 are correct only to the minute and so can give only rough results Madhava has, therefore, computed in place of the above, more s0plhisticated M001-sentences, correct to the second, for nine anomalistic cycles of the Moon (248 days) and set them out and 1.

A critical edition of this Table, which begins ith the sentence silam1 ।rdjॉ07 5riye, has been added to the present edition as Appendix 1. ८d l0c mnemonic expressions independent of each other and having no contextual sequence. Quite often, they do not have any logical sense either. This nature of these sentences, apart from creating conditions for errors to crep in, also debars the correction of such errors with reference to the context or grammar. The same holds good rutatis 1714tardis in the verification of doubtful readings. Two methods have been enunciated in the Imanuscripts of these Sentences for the correction of errors and for the clarification of doubts. These methods have been duly 10ticed at the close of the edition of the Sentences and have been demonstrated by concrete examples Manuscript Material Text : The present edition of Spl1410c01d/apti is based on its only available manuscript which originally belonged to the collection of the Namputiri brahman house of Kuta11ur Mana in S. Malabar (Kcrala) and is now deposited in the Kerala University (Oriental Research Institute and Mss. Library, Trivandrum, as its Ms. No. 1055 A. The work is inscribed in Malayalam script on the first two folios of this palm-leaf codex of Jyotisa works, 10'x2}", with 11 1ines a page and about 45 letters per line. The mamsucript is old and slightly damaged and the edges are all frayed. The writing is small, clear and inked. It has passed through the hands of a revisor whose corrections can be identified by their not being inked. The text presented is generally correct and free from errors . Besides the Splurac८॥1drapti, which is catalogued as A, the codex contains the C. M4/1॥rtara tr1d by Govinda Parame5vara ; E. $04015ak/riyayidhi ; F. D. Acard.50ाigral८ by Mult2rt(0p47casika ; (G.

Palace Collection Trivandrum, and is inscribed on a few stray uncatalogued leaves at the end of Ms. No. 4116, Drggapitakram10. Ms. D occurs as the third work in a codex of astronomical works beginning with the P८ictab0d/ld preserved in the private collection of Elamprakkotatu Mana, Eravor (mear Tripunithura, Cochin) and carries the inscription

All the manus cripts exhibit minor differences from one another and sometimes present entirely different vdly/0s, but to the same import. Possibly these variants go back to the author himself In continuation of the Spl॥tac01drapti, the text manuscript contains two short tracts. The first depicts the Yugd-bloga-diruwas (Zero-corrections per aeon) of the planets correct to 1/60th of a of Haridata1 and seem to have been extracted here for some practical use an account of their forming an independent unit The second tract, which is more interesting, sets out large chunks of full days, ranging from 16,45,705 to 248 with their ८ll।'uwd for the Moon correct to the second. These are obviously intended for the subtraction of days in chunks and correction of the results by the application of the corresponding dlhruwas in the computation of the Moon. The dhr'uwa of the last of these chunks, viz. 248 (dewal prajों0 1010171), is given as 0r–27०-43'-29', the mnemonic sentence therefor being d/li।'0'lant bl८.stur० iोंari . This mnemonic resembles closely the corresponding mnemonic of Madhava's Moon sentences, which reads as d/hiragir blastura, indicating the possibility of common authorship Both these tracts have been included in the present volume as Appendices [ and III, in the form of Tables, with the numerical figures of the sentences duly set out against then 1. 2.

Till recently, he was unknown to the scholarly world, especially outside his native land. He hailed from the village of Sangamagrama, the modern Irinjalakkuda, near Cochin, in Central Kerala, the name of his house being IraHni ninna palli to be identified with one of the two still existing houses in the village, named Irinnanavalli and IrinnSrappalii. This information the author gives in his Venvdroha and is corroborated by his commentator Acyuta. 1 Madhava was the teacher of Paramesvara, (AD 1360-1455), the promulgator of the Drgganita school of Kerala astronomy and is frequently quoted in the mediaeval astronomical literature of Kerala with the appellation of Golavid ( 'Adept in Spherics' ). Thus Nilakantha Somayaji (I444.I545 A.D.), while referring to Paramesvara in his Aryabhapya- Bhusya says : Paramesvaras tu ... Madhavadibhyo 'Golavidbhyo' Ganita-gola-yuktir api bnlya eva samyag grhitxci ... . 2 Acyuta Pisarati uses the same appellation for Madhava in the introductory verse to his Sphutanirnaya : vande 'golavidaf ca Madhavamukhan etc Works of Madhava , The Venvaroha? depicting a facile method for the computation of the Moon and the Moon-sentences, 4 commencing with silam iT^TTJTfa hW Smfasramfr TW: U (verse 13) Com. in Malayalam . *Rto f^TT SffSlfafec^ ^ On this, see K.V.

Ed. as Appendix I, below, has been shown lately1 that he is the author also of 1.0g10praka7012 in six chapters, 4ganita, an extensive work on the computation of planets , using novel methodologies and two short tracts entitled Madhyaा71a7aya70prakara and Mahajyam10)"0710prakara. Still. another work possibly composed by him is the Gollavadu , which seems to have helped to stabilise his appellation as 'Goldwid'. Sp/lt/[0c07drapti, edited here, is the latest addition to this works .* Besides the said full-fledged works, a number of stray verses of Madhava are quoted by later astronomers like Nilakantha Somayaji Nārāyana, commentator of the Llavat, Saikara, commentator of 7antrasaiोgraha etc. One of his significant contributions to mathe Imatics, known from these quotations , is his e nunciation of formulae value of 7 by the method of indeferf ate series, a method which was re-discovered in Europe mearly three hundred years later by James (Gregory ( 1638-75 A. D.) and (Gottfried Wilhelm Leibmit7 (1646-1716 A. D.).* His iye por८ऽpura-1ya]yur contains the emun ciation, probably for the first time in India, of the formula for the Sime of the sum of two angles, sine (A+B)=sin A. Cos B + Cos A. Sime B. The study and interpretation , in terms of modern mathe of the enunciations of Madhava in his stray verses and in his full-fledged works is bound to yield valuable results in the history of Hindu astronomy Certain directions given in the Sphutac८ndrapti give a general indication of its date of composition. Thus, for the calculation of the Mean Sun we are asked to subtract from the current Kaliday the the editon of 1e११varoha, pp. 8-9: History of ८1str071०71y, (Hoshiarpur, 1972), pp. 51-52, 151 pp. 32-33, 117, with a view to 3.

If there be further days, the number of such days has to be multiplied by the mean daily motion and added (verses 20-21). This would show that the work was composed about this time. This date would be 15,02,008 days (Kali 4112, A.D. 1010) plus 5180 anomalistic cycles of the Moon (390 years), i.e., about 1400 A.ID) Madhava's recently identified work, 4garita, also gives a clue to his date . Indicating the sodhyabda -ऽ ('deductive years') for the computation of the planets, the author states : C. 1360 to 1318 1320 शाकाब्दात् ‘नरलोको'नाद् राघवैधत्सुना कुजः । 1340 “दिव्यलोको'ननीलाप्रैस OF TRUE MOON 1158 ‘हेमपुण्यो'नशाकाब्दात् ‘नवलोको'नसारङ्गर्गजैराप्ते गुरुर्भवेत् । तत्वभजिते वधः ।। सारवैगवरैर्भगुः ।

In consonance with the principle of 50d}}]yabda-s, these figures represent the largest number of years possible to be cut of for the different planets at the time when the work was written. The date of composition of the work would thus, be just ahead of the largest 'deductive year' mentioned, which in the present case, is A.D. 1418. 1276 ‘तीर्थप्रियो'नशाकाब्दाद गन्धमििजते तम: ।। A clue to the date of birth of Madhava is provided by that of his younger contemporary and pupil, Parame5vara who was borm From the above considerations Madhava have lived between A.

I am indebted also to the authorities of the Kerala University Oriental Research Institute and Manuscripts Library, Trivandrum, and Shri Trātan Namputirippād of the Elamprakkotatu Mana, Eravoor, for permitting me kindly to utilise the 1manuscripts in their possession, for this edition. The credit for the meat printing and get-up of this volume goes to the W.W.R.1. Press, Hoshiarpur. 15 Vishweshvaranand Institute, Hoshiarpur, Independence Day, August 15, 1973 I N T R 0 0 U C T I 0 N (OBJECT OF THE WORK 1method which would enable one to compute True Moon at in tervals of about 40 minutes cach, throughout the day. Now, amongst the celestial bodies, the Moon has not only the fastest motion, of about 13० per day, but also the greatest variation in motion. On account of this, True Moon for any specific moment if calculated by the rule of three using its true position and motion, at sunrise, as is generally done in the case of the other planets, cannot be expected to give correct results, the possibility of error being as large as 10 windikas. Even if the calculation is done using its true position and m10tions at sum rise and Sunset, the results obtained would still be far from acc:1rate. Accurate results can be obtained only by the Second or third differences, which, however, would entail inordinate labour. The method described in the present work obviates this labour and makes it possible to read out from a chart the True longitude of the Moon accurately at nine times a day, at intervals of a little over six and a half 74lka.s (2 hrs. 40 min.). From the True Moon at the quarter (40 min.) of these intervals, the True Moon at any moment falling within any such 40-minute-interval can be calculated by the rule of three, to get remarkably accurate results The fact that calculations are made correct t0 seconds adds to the accuracy of the results Certain peculiarities of the popular Moon-sentences (C011dra wakyas) of the Kerala astronomer Vararuci have provided the clue to our author for devising the meth0d described here. The said sentences comprise of 248 expressions couched in the Kat0payindi motation and give the longitudinal positions of the Moon for cor। secutive days contained in 9 ful11umar anomalistic cycles of 27 days, 33 7alikas and 16-24/55 winadikas each. These Ca11dra1akyas can be used from the moment when the amormally is zero, '.e., from the com junction of the Moon and its Higher Apsis (Candra-Turig८-yoga), which occurs at the end of every anomalistic cycle, which may be at any time of the day and not necessarily at sunrise At sunrise, say, on the current day, suppose a full days and b part-day have gone by since when the anomaly was last Zero. This ould mear that we can commence using the Caा7dra)valk)'05, one per day, from the moment which is exactly (a+b) days before the current day. Now, let us consider a moment which is b day before the current day. Since b is only a fraction of a day, this Moment will fall in the previous day, its /141-wi7a4f being the s071e as the moment of the end of the cycle a days ago. So, if we add to the Moon's Dl।ruva (Zero correction) at the end of the cycle, the Moon-sentence equal to ८, the result will be the True Moon (Ca11dro-Spluta) for that Momment on the previous day Now, the above argument will apply not only for the end moment of the last cycle, but also for the end-moment of any cycle before that , the corresponding Momments being exactly (1 +b) days+1 cycle, (0-+b) days-+2 cycles, (a +b) days-+-3 cycles etc. before ७१॥rise on the current day, (i.e., the end of the final Kal:#dird, for the current day). Only, for every additional cycle by which the moment is pushed backwards , a zero-correction of 30-4'-72#', which is the D}}॥१५॥४0 for one cycle, will have to be deducted For mine such previous Zero anomalies (by the reckoming of which one full series of 248 days and 248 Ca71dravakya.s would be exhausted), True Moons can be obtained at nine Momments on the day previous to the current day, i.e., the last day of the Kalidind. The intervals between consecutive Monents will be a little more than 6 1alkds, and a quarter thereof, for which the longitudes could be calculated by the rule of three, would be about 40 minutes. If the true Moons at the nine Momments are required for the current day and the succeeding days, they could be had by adding the succeeding relevant Caा71drovakya in place of the vaky0 first used. For this reason, when the Momments, Vakya.s and True Moons for any day, during a 248 day period, have been calculated and duly entered in a Table, the Tables for the further days could be prepared with ease therefrom It is to be m७ted here that this method depends on the accident that an anomalistic cycle does not consist of a whole number of days, INTRODUCTION in which case, one would, again and again, be getting the same long It is again to be noted that, in order to secure a high degree of accuracy, the author has devised a new set of Moon-sentences, correct to the second, for use in the calculation of the Moon by the method set out in the present work, in place of the commonly used (C271drayakyas of Vararuci which are correct only to minutes. In actual working, the author has introduced several ingenious innovations with a view to lighten the labour involved and to arrive at quick results. Thus, by calculating backwards, he has arrived at an Epoch (Kha१140-di10), wi2., Kalidi10 15,02,008 (dinta707 715as y0) (verse 5). ८t 1e (21d (१/ whill a conjunction of the 140on and its Higher Apsis (C07dra-7ig0-Yoga) had occurred . Thus, am ano Imalistic cycle of the Moon commenced at sumrise, at the expiry of the said Kha110-di10, thereby removing the part-day, wi८., b of (a+b) days (vide supra), and enabling calculations with full days For computing the True Moon on any particular day, subtract the above K7011adli10 from the Kalidi70 for that day and find out the number of completed anormalistic cycles which have gone by subseuent to the epoch. For this, the remaining days (Khaा70-5es०) is asked to be multiplied by 6845 (ऽivadlnta) and divided by 188,611 (paryaptalrday), the underlying reason being that the period of a cycle is given by the fraction 138,611/6845 days which works out to 27 days, 33 7adlikds, 16-24/5 winadikas (verse 5). The quotient is called the 'First result' (4grimraphala). The further eight results are also noted by reducing the quotient progressively by 1, 2 etc 1. Of course this could be obviated by using. instead ['dyas, new 17akyas constructed for fractions of days and appropriately 2. 19 For a cri•ical edition of these Moon-sentences, whic 3.

Since the remainder left in the division for getting the full cycles gone by (verse 5) is really the number of days in the current cycle multiplied by 6845 ($iyadata), the said number can be retrieved by dividing the remainder by 6845.

The two items which go to make up these corrections are : (1) the M001's longitude at epoch, and (2) the additional longitude due to the cycles which have gone by For facilitating calculation, the author has isolated two lumps (Kha11a.s) of cycles and indicated the corrections due to them : (i) 5105 (71a71a kārata) cycles, the longitude due to which added to the Zero-correction at the epoch, wiट., Kaliday 15,02,008 (d17010717anu5asy0), gives a result ending in complete minutes, being 57-24०-47' (ऽ0trwa141 ।ram1al), and (ii) 69 (lt) cycles, the longitude due to which, again ending in complete minutes, is 77-1०-44” (wiऽvaikarta11;al). For each additional cycle, the longitude is given as 3०-4-6 3' (verse 10), which is 1/69 of 77-1०-44” In actual practice, however , it is sufficient to calculate the correction for the First result (4grim10plhala, verses 5-6); Since the further cight results are successively 1 less than the First their corrections can be had by diminishing the previous corrections by 3०-4'-6 22 23 2 example taken 71 10 35 37 18 4 2 30 45 57 24 50 17 44 calculated 29 as 13 56 40 23 21 ab0ve (iii) 6 (iv) 6 (v) 6 (vi) 5 (vii) 5 (viii) 5 (ix) 5 Table of Longitudes 10 17 24 30 37 44 50 57 The above results have now to be adapted for nine Momments in the Kaliday taken, in order to enable the corresponding longitudes to be read out with ease. For this the nine Momments are rearranged in the ascending order and posted in a table with the corresponding Walyas, Yalky0ऽ0ikhyas and Dlruwas against each.

Rationale : The sum rises at the rate of 10 wind(likतs earlier or later. as the place is 1० east or west of the standard meridian and this is additive or subtractive, respectively. to get the true [0];ru१७८k८l८. Expert astronomers find this time by various means, and usually express it in terms of correction to the Mean Moon, which, obviously, is negative for the east, and positive for the west . This is transmitted through tradition to succeeding astronomers This can be re-converted into windika s by multiplying the Moon's correction by 25 and dividing by 56. since the mean motion in 255 witadikas is 56 Since the correction-viradikals and the Moon's correct1०n are opposite in sign, the sign is asked to be reversed. 38 1. छाया वैषुवती यत्र द्व्यङ्गुला तत्र केवलम् । गुर्वक्षरात्मकमिदं विद्याच् ततो न्यूनाधिकायां तु तत् स्यात् तदनुपाततः । सायनेऽर्केऽजजूकादौ ज्ञेया तस्य धनर्णता ।। ३२॥ चरदलं तेषामेकविधत्वे स्यादेकीभूतानि तानि सः । भेद एकस्य' चेत्तस्य चापरैक्यस्य चान्तरम् ।।३३॥ चरार्धमात्रसंस्काराद् दिनार्ध त एते धुवकालाः स्युवाक्यकालाः सुसस्कृताः । [ चन्द्रस्फुट: ] कृतम् ॥३१॥ 15 दिनमानाल्लधीयांसस्तेऽहन्येव, निशीतरे । is i eads ‘शुकनाडिकाः ॥३४॥ तेषु स्वभ्रवयुक्तानि वाक्यानि स्फुटशीतगुः ॥३५॥ ततस्तदन्तरालेषु स भवत्यनुपाततः । चापरं, both of which are तस्य तत्कालगमनं यतस्तद्भद्वितयान्तरम् ।। ३६।। For एकस्य the ms. reads ऐक्यस्य and for चान्तरं at the end of the wrong. The emendation is in consonance with the parallel lines in the author's Wepyrol4a. 31. It is to be moted that the above (table) gives the half-ascen and pertain to a place where the cquinoctial shadow is two fingers 39 32. (When the equin0ctial shadow of the place in question is) 1ess or more than (2 aigult.s), (the half-ascensional difference) will be proportional (to the shadow). Its positive or negative nature is to be underst00d from the Sayana-Sum being in (the six signs) from aries (ajadi) or from libra (inlkadi) 33-34a. When the sign of all the three is the same, (the total correction) is their su11 ; when one is different, (thc total correction) is the difference between it and the sum of the other two . The Walk y0 kalा-ऽ duly corrected (as above) will be the ( correct) Dhruwakala 34b-35a. Fifteen (81८८) 141ikas corrected merely by the half ascentional difference will give (the length of) the half-day. Those (Yaky07/kala-s) which are less than the length of the (full) day (i.e., twice the half-day as found above) will fal during daytime and the other (Wakyak८ld-s) will fa11 during might-1ime (True M001) 35b-36. The sum of the (relevant) Valk y'01ऽ (Moo1-sentences) and the (relevant) D/truva.s will give the True Moon-s (at those Walkyakala-s). The True Moon (for times) in between (two Waky८ kala-s) will have be calculated by interpolation. The Moon's motion during a11 interva1 is the difference between the two (relevant) True Moons (and hence the said interpolation) 1. This would correspond to a region having a latitude of 9}°, like Central Kerala, from where the author of this work hailed 221 [ इष्टकालस्फुटानयने मागन्तिरम् । 220 ‘कठोरं’ ‘निष्ठुरं' चैके क्षिपन्त्यूध्वं त्यजन्त्यधः । यथोक्तवाक्यसंख्यायां ‘सुखं' 'दुःख'मतोऽन्यथा ॥३७॥ 27 विदधीतैवमेवार्के स्वर्ण 28 तदन्तरं निहत्येष्टनाङया ‘नत'हृतं ततः । धनर्ण विदधन्त्यूध्र्वमधश्चादावथोदिते ।।३८।। 60 1550 [ इष्टकालरविस्फुटम् ] तथा तन्मध्यमे कृत्वा कुर्याद्वा तत्स्फुटक्रियाम् ॥३९॥ विदित्वास्य गतिं स्फुटाम् । स्वोच्चोनमध्यार्कककिनक्रादिषटकजा । कोटिज्या'त्माशय'हृता गतिर्मध्याऽस्य तत्स्फुटा ॥४०॥ (Am10ther meth0d for True M100n at any time during the interwal) 37.

In the case of the Sun, too, (its True position at any desired time) can be computed using its True Motion. Computation of the True Sun can be done also by finding the Mean Sun (at the time) using its Mean Motion 40. R (Cosine of the Mean Surn-71i115-Higher Apsis is to be divided by 1550 (1710:50]'t) and the result applied to the Sun's Mean Motion, positively (when it is) in the six signs beginning with Cancer (Karki) and negatively in the six signs beginning with Capricorm (Wokra).

This verse occurs among the ex'ra has been inserted here in consonance with author's Yepwarolha. verses after the work and itऊ parallel verse in the 41. Alternatively, take the reading for Sun-7iruऽ-Higher Apsis in the Sine Table beginning with j८7erाd. Add to it 1/31 (yag८is०) of itself and apply the result, taken as seconds, to the Mean Motion of the Sun, its being positive or negative being the same as before, (i.e., as stated previous verse). (The Sun's True Motion is got) 42. The two positions of the True Sun (in its course) correct to seconds, when its daily motion is exactly 1 ", are 10-270-3'-10 ' (istaiga71asakho miryam), and 6-8०-56-50” (ris5esaा71adamarinut) 43. The Mean Sun-s at these positions are , according to Aryabhata, 10-25-4-25” (5auriva 705 5ir07071yah) and 6-100-55-35” 4. When the (true) position (Split41a) (of the Sun) is equal to its Higher Apsis, it will have the slowest motion. And, when it is equal to its Lower Apsis, it will have its fastest motion 45. The corrections prescribed for the Dhr't८yakal45 are to be (computed and) applied also to the mnemonics for the Sun's transits (from one sign to another) so that correct results might be obtained 46. This correction can be applied inversely also to the 4harga10 (Total number of Kalidays up to the current day). When corrected in this manner, it will give the True 4largapor which elapsed at sumrise (on that day) 1. This is the table of the Mandajys of the Sun enunciated in the Gralacaranibandh८॥८ of Harridata (ed. K.V. Sama, K.S.R.

For यन्मया नोक्तमन्तररा, the ms. reads, यन्मयेनान्तरान्तरा । The correction follows its parallel verse in the author's Veruvarolha. 3. After this occur 7} verses, obviously written by Mādhava himself, (see Preface, p. 10), 2} of them being revised versions of verses in the text. The rest have been fitted into this edition on the basis of the parallel verses in the author's Yeएाvarold. (Node) 47-48. The first result (4gri70plalld of verses 5-6) is reduced by 5161 (karta71 karm10) and multiplied by 87 (sodar10). From the result subtract 35 (71210) and add to the remainder its 277th (staliasara) part. (The result obtained is in ) minutes and * is to be subtracted from 6 to get (the position of) the Node. Its position for the (different) Wakyakala.s is to be computed proportiomately using the /alk yers८ik/hya-s in the same manner as that prescribed for the Sun.1 (Conclusion) 49. Stating but this much and that in a succinct manner, possibly certain details might have been left out by me, at places, under the presumption that those (details) are (generally) known May all those (details) be before your (mind's eye) 50. With a view to dispel the doubts of good men, the motion of the Moon has been set out in a proper manumer, concisely, by a Iman of intellect (which I consider myself to be) . 45 51. By the very same person who composed the set of Moon sentences, beginning with ऽfla71 rajोंal7 6riye (12-2-35"), correct to the seconds, has this work, t00, been composed (Thus ends THE COMPUTATION OF TRUE M00N by Mādhava of Saigamagrāma) minutes per Moon's anormalistic cycle. At 5161 Moon's anomalistic cycles after the Khapda-di१८, the Kep८ for the Node is (35-+-3527) minutes, negative. Hence the subtraction of 35. Since the Node's motion is retrograde, the total result is to be subtracted from the position of the Node at the beginning of Kali, which is 6 r06is. The use of proportion for the days gone during the current cycle is obvious, the motion of the N०e being uniform, 7akya W०. 1. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10 . 11. सङ्गमग्रामज-माधवकृतानेि विलिप्तादि-चन्द्रवाक्यानि Val.ya as Big० शील राज्ञ: श्रिये धिगिदं नश्वरम लोलः पुरुषो नार्याम्' तपस्वी वैदिक: स्यात सेव्याळका किन्नरैः दीप्रो दिने भास्कर धर्मरम्यं सुराष्ट्रम् स्तनौ लीलानुकूली पुत्रादौ न विरागः शौरिः समर्थ एव दुष्टैर्देशोपद्रव : * 0 1 46 1 2 4 12 24 6 18 14 27 10 24 7 21 na' wa' 2 8 21 44 19 8 12 33 8 57 58 35 39 33 16 17 28 59 2) 25 This critical edition of the Walkyas is based on the following four independent mss . : A.
