Rabbenu Bachya ben Asher lived in Spain in the mid 1300's. He was a student of the Rashba (Rabbi Shlomo ben Aderet), who was a student of the Ramban (Rabbi Moshe ben Nachman, or "Nachmanides"). As such, he was deeply immersed in both the revealed and esoteric sides of Torah, strongly influenced by his teacher and his teacher's teacher. Rabbenu Bachiya's classic work in "Rabbenu Bachiya on the Torah", an exquisite, classic commentary on the Five Books of Moses.
Rabbenu Bachiya is buried near Hukuk in the Upper Galilee in a cave alongside his students (monument above the cave in the photo below). May his holy memory protect us, amen.
