Complete Works of Euclid, Vol. 7 (Optics and Catoptrics)

p. 150, 15 ἀποπαλθεῖσαν] ἀ|παλθεῖσαν cod. 1, ἀπαλθεῖσαν 3; p. 152, 17 αὐτὸ μὲν] αὐτό| cod. 1, αὐτό 3, 7; p. 168, 1 τοῦ] τῷ cod. 1, 7; p. 168, 2 Η] ἦτα 1, 7; p. 168, 4 ΔΓ] Δ 1, 7; p. 168, 18 ἡ δέ — 21 ὁρᾶται] later inserted in cod. 1, om. 7; p. 168, 21 after ὁρᾶται adds καὶ ἀπώτερον φαίνεται τὸ Δ· τὸ Δ ἄρα ταπεινότερον φαίνεται τοῦ Γ, τὸ δὲ Γ τοῦ Ζ cod. 1, 7 (cfr. V); p. 288, 3 τρίγωνα] om. 1, 3, 7; p. 294, 11 θῇς] ς Θ cod. 1, θῇ 3; p. 294, 12 κέντρου] κ̅- cod. 1, κύκλου cod. 3, but corrected, nor indeed can cod. 7 have been described from the older cod. 3; see p. 146, 15 τό] cod. 1, 7, τοῦ 3; p. 148, 10 ἀναγκαζομένους] cod. 1, 7, ἀναγκαζομένου 3; p. 148, 14 ἐστι] cod. 1, 7, om. 3. Codex 3 was corrected to the likeness of codex V by a recent hand; see p. 148, 20 at τό in margin γρ. μή; p. 150, 23 at ἑαυτῆς in margin γρ. πρὸς ἀντίληψιν τῶν ὁρατῶν; p. 144, 1 at ὄψιν written above by 1st hand ὁ Εὐκλείδης; p. 152, 25 at καί in margin by 1st hand περί; p. 158, 22 after ΔΖ later added τῶν ἴσων ἄρα καὶ τὰ ἑξῆς.

Perhaps cod. 21 was also described from cod. 1; for at p. 288, 3 it omitted τρίγωνα and at p. 288, 17 for MN it alone has MH, but in cod. 1 at this place N is written in such a way that it is very similar to the letter H.

At p. 190, 14 the words ὅλου τοῦ in cod. 14 were almost consumed by worms. Now, since cod. 8 omits ὅλου and cod. 9 left a lacuna, cod. 13 left a lacuna for ὅλου τοῦ (in which αὐτοῦ by 2nd hand), they were described from cod. 14; cfr. p. 236, 8 προσιόντων μέν] πλησίον corrected into πλησίον 14, πλησίον 13 (προσιόντων μέν by 2nd hand), πλησίον 8, 9. That cod. 20 pertains to the same can be concluded from the varying spellings brought below; see p. 144, 14 τοῖς] τοῖς φωτοῖς, deleted τοῖς φω, 14, τοῖς after a lacuna 13, τοῖς 9, τοῖς φωτοῖς 8, 20; p. 146, 15 εὑρήσομεν] 8, εὑρήσωμεν 14, 9, 13, εὑρήσωομεν 20; p. 146, 18 ὄντος] ὄντως 14, 9, 13, 20, ὄντῶς 8; p. 148, 20 τό] om. 14, 8, 9, 13, 20; p. 150, 4 καί] 14, 13, 20, om. 9, by 2nd hand in cod. 8; p. 150, 11 κατεσκεύακεν] 8, 13, 20, corrected from κατεσκεύασεν 14, 9; p. 150, 18 ὄσφρησιν] 8, ὄσφρισιν 14, 9, 13, 20; p. 152, 1 κατά] 9, 20, κατασκευασμέναι 14, κατασκευασμέναι 13 and 8 (corrected by 2nd hand); p. 152, 7 ὑψηλοτέρα] 9, corrected from ὑψηλωτέρα 14, 20, ὑψηλωτέρα 8, 13; p. 152, 8 κεῖσθαι] 14, 8, 9, 20, κείσεται 13; p. 152, 10 γεγραμμένης] 8, 9, -μέ- consumed by worms 14, lacuna 13 (corrected by 2nd hand), γὰρ εμμενης 20; p. 152, 23 ἡ περί] ἣν περί 14, 8 (corrected by 2nd hand), 9, 13, 20; p. 172, 6 ΒΔ] 14, 8, 13, Δ 9; p. 190, 14 ἤ] ἐστι καί 14, 8, 9, 13 (corrected by 2nd hand).
