Aaron ben Jacob ha-Kohen


Aaron ben Jacob ha-Kohen was a Provençal rabbi, one of a family of scholars living at Narbonne, France, and who suffered the expulsion of the Jews in 1306.
He emigrated to Majorca, and there, some time before 1327, composed a ritual work of great merit bearing the title Orchot Hayyim. The first part deals chiefly with the laws concerning the daily prayers, the Sabbath, and the festivals, and was published in Florence in 1752. The work is a compilation of Talmudic laws and discussions rather than an original system, and was conceived on a plan similar to Jacob ben Asher's great code, the Arba'ah Turim, which appeared soon afterward and superseded it as a ritual guide on account of its more practical character. The Orchot Hayyim, however, contains some ethical and doctrinal chapters which are not found in the Arba'ah Turim. Aaron ha-Kohen was especially fond of mystic lore and of rabbinical discussion. A less strict legalist than Jacob ben Asher, Aaron's Orchot Hayyim is of greater value to the student of literature than to one who seeks practical decisions.
A different work, the Kol Bo, is considered by some to be an abridgment of Orchot Hayyim ; according to others, Kol Bo is a first draft of Orchot Hayyim.
