231. The magic mirror in Rome was said to have been set up there by Vergil, who was at one time reverenced, not as a poet, but as a great enchanter. The story occurs in the Seven Sages, in the Introduction to his edition of which Mr. Wright says, at p. lix., 'The story of Virgil's tower, which was called salvatio Romae, holds rather a conspicuous place in the legendary history of the magician. Such a tower is first mentioned, but without the name of Virgil, in a Latin MS. of the eighth century, in a passage published by Docen and republished by Keller, in his introduction to the Sept Sages. Vincent of Beauvais, in the thirteenth century ... describes Virgil's tower; and it is the subject of a chapter in the legendary history of Virgilius.' See also the other version of the Seven Sages edited by Weber, and reprinted in Mätzner's Sprachproben, i. 254; where the mirror is mentioned.
Gower tells the story of this mirror in his Confessio Amantis, bk. v. It occurs also in the Chronicle of Helinand, and in the Otia Imperialia of Gervase of Tilbury; Morley's Eng. Writers, iv. 225. Warton notes that the same fiction is in Caxton's Troybook, bk. ii. ch. 22. It also occurs in Higden, Polychronicon, bk. i. c. 24.
232. 'Alhazeni et Vitellonis Opticae are extant, printed at Basil, 1572. The first is supposed by his editor to have lived about A.D. 1100, and the second to A.D. 1270.'—Tyrwhitt. Hole's Brief Biographical Dictionary has the notices—'Alhazel or Alhazen, Arabian Astronomer and Optician; died A.D. 1038'; and—'Vitello or Vitellio, Polish Mathematician; floruit circa 1254.' See also the remarks in Warton (Hist. Eng. Poetry), on the Clerk's Tale. Alhacen (sic) is mentioned in Le Rom. de la Rose, l. 18234. In l. 18376 of the same, we find the very phrase: 'Par composicions diverses'; and again, in l. 18387: 'Par les diversités des angles.' Mirrors are there described at length. R. Scot, in his Discoverie of Witchcraft, bk. xiii. c. 19, declares that 'the wonderous deuises and miraculous sights and conceipts made and conteined in glasse, doo farre exceed all other.'
233. Aristotle, the famous Grecian philosopher, born B.C. 384, died 322. writen in hir lyves, wrote in their lifetime. Observe that writen is here the past tense. The pres. pl. is wryten; pt. s. wrat, wrot, or wroot; pt. pl. writen; pp. writen.
238. Thelophus. Telephus, king of Mysia, in opposing the landing of the Greeks in the expedition against Troy, was wounded by the spear of Achilles. But as an oracle declared that the Greeks would require his aid, he was healed by means of the rust taken from the same spear. Chaucer may easily have learnt this story from his favourite Ovid, who says—
'Telephus aeterna consumptus tabe perisset
Si non quae nocuit dextra tulisset opem.
Tristium, lib. v. El. 2. 15.
And again—
'Vulnus Achilleo quae quondam fecerat hosti,
