Nathan Judah ben Solomon was a Provençal Jewish physician and scholar of the fourteenth century. His Provençal names were En Bongodas and Bonjues and he was probably a native of Avignon, where lived many other members of the Nathan family. Judah, like all the other members of his family, added to his father's name the formula "of the race of Ben Jesse," which is probably an allusion to the house of David, from which several Provençal families claimed to be descended.
