Today is the yahrtzeit (anniversary of the passing) of Rabbi Don Isaac Abravanel (1437-1508), one of the leaders of Spanish Jewry at the time of the 1492 expulsion. A minister in the king's court (after having served as treasurer to the king of Portugal), he chose to join his brethren in their exile. He began writing his extensive and highly regarded commentary on the Torah in 1503 in Venice (where it was published in 1579).
