Jacob ben Asher (c. 1270 - 1340), also known as Ba'al ha-Turim as well as Rabbi Yaakov ben Raash (Rabbeinu Asher), was an influential Medieval rabbinic authority. He is often referred to as the Ba'al ha-Turim ("Master of the Columns"), after his main work in halakha (Jewish law), the Arba'ah Turim ("Four Columns").
