1240 - 1292 ABRAHAM ABULAFIA (Spain)
One of the first kabbalists. He was opposed by Solomon Aderet who felt that he was almost posing as a messianic pretender. Abulafia analyzed the Hebrew alphabet and the letters in God's name, calling it chochmat ha zeruf (science of letter analyzation). As a young man he traveled, searching for the legendary Sambation River.
