ABRAHAM BEN JUDAH:
A physician who wrote in Hebrew a medical work, "Mareot ha-Shetanim" (Aspects of the Urine); date of birth and death unknown. According to a statement in the introduction, the author intended his work to be a guide for young practitioners and a reference book for laymen. He promised, also, to make a compilation on this same subject, drawn from the writings of the best authorities. It is not unlikely that his book is only an extract from the work on urine written byIsaac Israeli, who died about 950.
