Euclid ibn Naucratis ibn Bernikes, master of the Geometry (al-Jumatriyya), that is, geometry. Ibn al-Nadim counts him among the mathematical philosophers, and as earlier than Archimedes and others ².

His book on the principles of geometry is called "al-Istarushiya". al-Hajjaj ibn Yusuf ibn Matar translated it twice: the first is the Harunian translation, and the second is the Ma'munian translation, on which people rely ².

Ishaq ibn Hunayn also translated it, and Thabit ibn Qurra al-Harrani revised it. Abu Uthman al-Dimashqi transmitted some treatises from it ².

Ayun commented on it and explained its doubts, and al-Nayrizi wrote a commentary. al-Jawhari has a commentary from its beginning to its end, and al-Mahani wrote a commentary on the fifth treatise ².

al-Kindi mentions that the book was composed by a man called Ablinus the carpenter, and that he drew it in fifteen sayings. When it grew old and was neglected, one of the kings of Alexandria asked for the science of geometry, and Euclid was in his time. He ordered him to revise it and explain it, and he did, and so it was attributed to him ².

Then Basqalaws, a pupil of Euclid, found two treatises, the fourteenth and the fifteenth, and presented them to the king, and they were added to the book ².
