I therefore agree with Mr. Brae that the 40th Conclusion would have done better for Part iv., though I do not agree with him in rejecting it as spurious. This he was led to do by the badness of the text of the MSS. which he consulted, but we can hardly reject this Conclusion without rejecting the whole Treatise, as it is found in all the oldest copies. By way of illustration, I would point out that this is not the only difficulty, for the Conclusions about astrology ought certainly to have been reserved for Part v. These are Conclusions 36 and 37, which concern the 'equaciouns of houses'; and this is probably why, in three of the MSS. (viz. L., N., and R.), these two conclusions are made to come _at the end of the Treatise_. There is nothing for it but to accept what we have, and be thankful. § 24. EXTANT PORTION OF THE TREATISE. If, then, the questions be asked, how much of the Treatise has come down to us, and what was to have been the contents of the missing portion, the account stands thus. Of Part i. we have the whole. Of Part ii. we have nearly all, and probably all that ever was written, including Conclusions 1-40 on astronomical matters, and Conclusions 41-43 on the taking of altitudes of terrestrial objects. Possibly Conclusion 46 is to be added to these; but Conclusions 41_a_-42_b_ are certainly spurious. Part iii. probably consisted entirely of tables, and some at least of these may very well have been transmitted to little Lewis. Indeed, they may have been prepared by or copied from Nicholas of Lynn and John Somer, before Chaucer took the rest in hand. The tables were to have been (and perhaps were) as follows:-- 1. Tables of latitude and longitudes of the stars which were represented on the 'Rete' of the Astrolabe. Specimens of such tables are found in MSS. 2. Tables of declinations of the sun, according to the day of the year. 3. Tables of longitudes of cities and towns. 4. Tables for setting clocks and finding the meridian altitudes (of the sun, probably). Such tables as these are by no means lost. There are MSS. which contain little else, as e.g. MS. Hh. 6. 8 in the Cambridge University Library. The longitudes of towns are given in MS. Camb. Ii. 3. 3, at fol. 214_b_. Again, in MS. F. 25, in St. John's College Library, Cambridge, we find tables of fixed stars, tables of latitudes and longitudes of towns, tables of altitudes of the sun at different hours, and many others. Part iv. was to explain the motions of the heavenly bodies, with their causes. This was probably never written, though there is an allusion to it in Part ii. § 11, l. 12. It was also to contain a table to shew the position of the moon, according to an almanac; and such a table is given in the St. John's MS. above mentioned, and in MS. Camb. Ii. 3. 3, at fol. 143. This was to have been followed by a canon, and an explanation of the working of the Conclusion--'to knowe with which degree of the zodiac that the mone ariseth,' and 'the arising of any planete,' &c. The canon is partly accounted for, as regards the planets at least, by sections 44 and 45, and the 'Conclusion' by section 40. Part v. was to contain the general rules of astrology, with tables of equations of houses, dignities of planets, and other useful things which God and the Virgin might vouchsafe that the author should accomplish. Sections 36 and 37 tell us something about the equations of houses; but, in all probability, none (or, at least, no more) of this fifth Part was ever written. Tables of equations of houses, for the latitude of Toledo, are given in MS. Camb. Ii. 3. 3, at fol. 177, and elsewhere. Of the general rules of astrology we find in old MSS. somewhat too much, but they are generally in Latin; however, the Trinity MS. R. 15. 18 has some of them in English. On the whole, we have quite as much of Chaucer's Treatise as we need care for; and he may easily have changed his mind about the necessity of writing Part v; for we actually find him declaring (and it is pleasant to hear him) that 'natheles, thise ben observauncez of iudicial matiere & _rytes of payens, in which my spirit ne hath no feith_'; ii. 4. 36; (p. 192). § 25. SOURCES OF THE TREATISE. I next have to point out the sources whence Chaucer's treatise was derived. Mr. Halliwell, in a note at the end of his edition of Mandeville's Travels, speaks of the original treatise on the Astrolabe, written in Sanskrit, on which he supposes Chaucer's treatise to have been founded. Whether the Latin version used by Chaucer was ultimately derived from a Sanskrit copy or not, need not be considered here. The use of the Astrolabe was no doubt well known at an early period in India and among the Persians and Arabs; see the 'Description of a Planispheric Astrolabe constructed for Sháh Sultán Husain Safawí, King of Persia,' by W. H. Morley, in which elaborate and beautifully illustrated volume the reader may find sufficient information. Marco Polo says (bk. ii. c. 33) that there were 5000 astrologers and soothsayers in the city of Cambaluc, adding--'they have a kind of _Astrolabe_, on which are inscribed the planetary signs, the hours, and critical points of the whole year'; Marco Polo, ed. Yule, i. 399. Compare also the mention of the instrument in the 161st night of the Arabian Nights' Entertainments, where a translation which I have now before me has the words--'instead of putting water into the basin, he [the barber] took a very handsome astrolabe out of his case, and went very gravely out of my room to the middle of the yard, to take the height of the sun'; on which passage Mr. Lane has a note (chap. v. note 57) which Mr. Brae quotes at length in his edition. There is also at least one version of a treatise in Greek, entitled [Greek: peri tês tou astrolabou chrêseôs], by Johannes Philoponus, of which the Cambridge University Library possesses two copies, viz. MSS. Dd. 15. 27 and Gg. 2. 33. But it is clear, from his own words, that Chaucer followed the Latin, and I can point out[52] one of the Latin treatises to which he was very considerably indebted. This is the 'Compositio et Operatio Astrolabie,' by Messahala[53], of which copies are, I have no doubt, sufficiently numerous. The Cambridge Library has four, viz. Hh. 6. 8, Ii. 1. 13, Ii. 3. 3[54], and Kk. 1. 1, and there is another copy in St. John's College Library, Cambridge, marked F. 25. The title should be particularly observed; for the treatise is distinctly divisible into two separate parts, viz. the 'Compositio Astrolabii' and the 'Operatio Astrolabii.' The former begins with the words--'Scito quod astrolabium sit nomen Graecum,' and explains how to make an astrolabe, and how to inscribe on it the various necessary lines and circles with sufficient exactness. It is much the longer portion of the treatise, and (in MS. Ii. 3. 3) is illustrated by numerous diagrams, whilst the second part has no such illustrations. But it does not appear that Chaucer made any use of this former part, as his |
