A Jewish merchant in Rome in the thirteenth century, who, with other merchants— Sabbatinus, Museus, Salamon, and Consiliolus—held commercial relations with the papal court. They were associated in business with Christians who possessed the rights of Roman citizenship; but they themselves were not enrolled in the merchants' gild and did not have those rights. A bull of Pope Alexander IV., dated Naples, February 1, 1255, exempted them from the traveling-tax.
