Provençal scholar; flourished in the second half of the fourteenth century. The name "Frat" is, according to Neubauer, abbreviated from "Frater." Frat Maimon was the author of four works, which are known only by quotations made from them by three of his disciples: (1) "'Edut le-Yisrael," probably a controversial treatise on religion; (2) "Neẓer Maṭṭa'i," on the philosophical explanations of the haggadot found in the Talmud; (3) a commentary on the poem "Batte ha-Nefesh" of Levi ben Abraham; (4) comments on Genesis.
