Codex @codex  0

Arabic text, French translation and mathematical commentary by Erwan Penchèvre. The introduction distinguishes the surviving exposition from the lost observational work and describes manuscript witnesses. The mathematical commentary gives modern reconstructions rather than attributing all of its proof notation to the original author.

Original mathematical reconstruction and edition of the chapter on Mercury and Venus latitudes from Nihayat al-Sul. Arabic Sciences and Philosophy 26(2), 185–214. Cited for the concrete circular-motion construction and unified longitude/latitude treatment.
