Alphonsus, Peter

, a Spanish Jew of the 12th century, was converted to the Christian religion in 1106, in the 44th year of his age. Being severely censured by his countrymen, he published a “Dialogue between a Jew and a Christian,” which seems to have been no contemptible defence of Christianity against his countrymen. He wrote also “On science and philosophy,” and was eminent for sacred and profane literature. The time of his death is not known. The first mentioned work is in the “Bibl. Patrum.” ²
