E. 2 in St. John's College, Cambridge, contains (besides Chaucer's 'Astrolabe') a Latin treatise entitled 'De septe_m_ climatib_us_ expositio.' We find mention of the 'climates' also in MS. Camb. Ii. 3. 3, fol. 33 _b_, where a diagram appears representing a hemisphere, divided by parallels of latitude into 9 climates or belts, which, beginning from the equator, are as follows. 1. Inhabitabile propter Calorem. 2. Primum clima dia Meroes. 3. Secundum clima dya cienes. 4. Tertium clima di' alexandrios. 5. Quartum clima dia rodos. 6. Quintum clima dia romes. 7. Sextum clima dia boristenes. 8. Septimum clima dia rifeos. 9. Inhabitabile. This agrees with the list in the footnote on p. 221. There is a passage in Mandeville which well illustrates Chaucer; I quote the part of it which more immediately relates to the Climates. 'For the Superficialtee of the Erthe is departed in 7 parties, for the 7 Planetes; and the parties ben clept Clymates. And oure parties be not of the 7 Clymates: for they ben descendynge toward the West. And also these yles of Ynde, which beth evene a[gh]enst us, beth noght reckned in the Climates: for thei ben a[gh]enst us, that ben in the lowe Contree. And the 7 Clymates strecchen hem, envyrounynge the World,' &c. Mandeville's Voiage, ed. Halliwell, p. 186. See also Ptolemy's Almagest, lib. ii. As regards the longitudes of towns, it may be observed that in MS. F. 25 in St. John's College, Cambridge, the longitudes of Rome, Cordova, London, Paris, and Malta, are said to be 34° 24', 9° 30', 19°, 20°, and 38° respectively. These do not well agree together, but they suggest a reckoning from a meridian situated some 20° W. from that of Greenwich. Chaucer says nothing as to what meridian was used for reckoning longitudes from; and Messahala says, vaguely enough, that longitudes were reckoned 'a meridiano circulo ultime regionis habitabilis in occidente,' i.e. from the most westward habitable place, which possibly once meant Madeira. § 40. It is possible that this conclusion was really intended to belong to the Fourth Part of the treatise, and was written by way of instalment. See the Prologue, ll. 67-72. It is curious that in all the best MSS. (P. excepted) the last sentence should be incomplete. 13. This sentence is very awkward. It seems to mean--'and then set I the point of F upward in the same sign, because that the latitude was north, upon the latitude of Venus; that is to say, (I set it upward) keeping it in the 6th degree of Capricorn.' _Upward_ means inward, i.e. towards the centre or towards the north; the opposite being expressed by southward, or outward, or toward the border, as in l. 48 below. _Upon the latitude of Venus_ means that the point F of the compass was set above the second degree of latitude, so that the space between the legs of the compass became equal to 2 degrees, as said in l. 16. Lastly, the words _that is to seyn, in the 6 degree_, &c., are an explanation of the vaguer expression _in the same signe_. The repetition of the words _that is to seyn_, &c. (ll. 12 and 14), is intended to draw attention to the necessity of keeping _both_ legs of the compass in the same degree of longitude (A on the zodiac, and F to the north of it). 57. Possibly Chaucer left the sentence incomplete. The words 'thou shalt do well enough' may easily have been added by another hand to bring the sentence to an apparent, though not wholly satisfactory, conclusion. The colophon is written (in a later hand) in MS. A. at the bottom of the page, a part of which, after the words 'howre after howre,' is left blank. 41-43. I have mended the text as well as I could by inserting words, and adopting different readings. Nearly all the emendations rest on authority; see the Critical Notes. The text is not a good one, but I do not see why these sections may not have been written by Chaucer. For a definition of the terms 'Umbra Extensa' and 'Umbra Versa' see sections 5 and 6 of the Practica Chilindri of John Hoveden, published by the Chaucer Society. The _umbra extensa_ or _recta_ is the shadow cast on a plain by any perfectly upright object; but the restriction is commonly introduced, that the altitude of the sun shall exceed 45º. The _umbra versa_ is the shadow cast _perpendicularly_ downwards along a wall by a style which projects from the wall at right angles to it; the restriction is commonly introduced, that the sun's altitude shall be less than 45°. The _umbra versa_ is the one which appeared on the 'chylindre'; hence John de Hoveden explains how to calculate the altitude of an object by it. 44. This article and the next may possibly be Chaucer's. It is well known that he speaks of 'collect' and 'expans yeres' and 'rotes' in the Frankeleines Tale; Cant. Ta., F 1275, 6, the note upon which in the glossary to Urry's Chaucer may be found also in Tyrwhitt's Glossary, s.v. _Expans_; but it is worth while to repeat it here. 'In this and the following verses, the Poet describes the Alphonsine Astronomical Tables by the several parts of them, wherein some technical terms occur, which were used by the old astronomers, and continued by the compilers of those tables. _Collect_ years are certain sums of years, with the motions of the heavenly bodies corresponding to them, as of 20, 40, 60, &c., disposed into tables; and _Expans_ years are the single years, with the motions of the heavenly bodies answering to them, beginning at 1, and continued on to the smallest _Collect_ sum, as 20. A _Root_, or _Radix_, is any certain time taken at pleasure, from which, as an era, the celestial motions are to be computed. By 'proporcionels convenientes' [C. T., F 1278] are meant the Tables of Proportional parts.' To which Moxon adds, from Chamber's Encyclopædia, with reference to C. T., F 1277, that '_Argument_ in astronomy is an arc whereby we seek another unknown arc proportional to [or rather, dependent upon] the first.' Tables of mean motions of the Sun are given in Ptolemy's Almagest, lib. iii. c. 2; of the Moon, lib. iv. c. 3; of the Planets, lib. viii. c. 3; also in MS. Ii. 3. 3, fol. 88_b_, &c. 41_A_-42_B_. The fact that these articles are mere repetitions of sections 41-43 is almost conclusive against their genuineness. I do not suppose that sect 46 (at p. 229) is Chaucer's either, but it is added for the sake of completeness. THE CANTERBURY TALES. SOURCES OF THE CANTERBURY TALES. CONTENTS. § 1.
