Grandson of Isaac ibn Daud de Sola (No. 8); born about the close of the twelfth century; lived in Barcelona. He was a man of learning and wealth, and by his munificence greatly encouraged Hebrew scholarship in his native city. Family traditions mention him as the author of a work on the Mekilta and of several theological writings. He married Judith Benveniste. During the second half of the thirteenth century some of his relatives settled in Narbonne, Montpellier, and other parts of southern France, but his descendants in the main line continued in Spain.
