Yitsḥak Luria Ashkenazi (1534 – July 25, 1572) (Hebrew: יִצְחָק בן שלמה לוּרְיָא אשכנזי, English: Isaac ben Solomon or Yitzhak ben Shlomo Lurya Ashkenazi), commonly known as "Ha'ARI" (meaning "The Lion"), "Ha'ARI Hakadosh" [the holy ARI] or "ARIZaL" [the ARI, Of Blessed Memory (Zikhrono Livrakha)], was a foremost rabbi and Jewish mystic in the community of Safed in the Galilee region of Ottoman Syria. He is considered the father of contemporary Kabbalah, his teachings being referred to as Lurianic Kabbalah. The works of his disciples compiled his oral teachings into writing and spread his fame which led to his veneration and the acceptance of his authority. Every custom of the Ari was scrutinized, and many were accepted, even against previous practice. Luria died at Safed on July 25, 1572 (5 Av 5332). He was buried in the Old Cemetery of Safed (from wikipedia)
