Mordecai Comtino
Mordecai ben Eliezer Comtino (Hebrew: מרדכי כומטיאנו; lived at Adrianople and Constantinople; died in the latter city between 1485 and 1490) was a Talmudist and scientist.
The earliest date attached to any of his writings is 1425. The form of his family name is doubtful, and has been transcribed by modern scholars as "Comtino." Mordecai's biographer, Jonah Hayyim Gurland, uses the form "Kumatyano," a name which he found still in use in Turkey (Geiger, in "Wiss. Zeit. Jüd. Theol." iii.445; idem, "Melo-Chofnajim," p. 13). He was the pupil of Enoch Saporta, a distinguished Talmudist, known for his cultivation of the sciences and his tolerance toward the Karaites.
