a Spanish rabbi, in the 13th century, who professed astrology, and assumed the character of a prophet. He pretended to predict the coming of the Messiah, which was to happen in the year 1388; but fortunately he died in 1393, fifty-five years before the time when the prediction was to be fulfilled. ABRAHAM fulfilled. He wrote a book, De Nativitatis, which was printed at Rome in 1545.
