The "Book of Raziel: Sepher Raziel ha Malakh" is a significant work that explores the mystical and philosophical aspects of the Jewish tradition. It is believed that the book was created in the 13th century during the time of King Alfonso X, also known as Alfonso the Wise. This edition, published by Giovanni Grippo, is based on a Hebrew text and references older sources that are deeply rooted in Jewish mysticism. The book shows great similarities to the texts of the Torah and has connections to the "Sepher Yesirah" (Book of Creation), which was written between the 2nd and 6th centuries CE. Despite the various versions and translations of the work, the exact origins and historical contexts remain disputed, making it a fascinating subject of study for those interested in philosophy and religion.
