Sefer Raziel HaMalakh (Hebrew: ספר רזיאל המלאך , "the book of Raziel the angel") is a grimoire of Practical Kabbalah from the Middle Ages written primarily in Hebrew and Aramaic. Liber Razielis Archangeli, its 13th-century Latin translation produced under Alfonso X of Castile, survives.
Like other obscure ancient texts such as the Bahir and Sefer Yetzirah, Sefer HaRaziel has been extant in a number of versions. The book cannot be shown to predate the 13th century, but may in parts date back to late antiquity insofar as its title is mentioned in another magical work of late antiquity: The Sword of Moses.
The book claims to have been revealed to Adam by the angel Raziel. Critical historians regard it as a medieval work, most probably originating among the Ashkenazi Hasidim, as citations reliant on the main body content of the work as we receive it begin to appear only in the 12th century. At least one section was available to Ibn Ezra before 1153, when he finished his commentary to Exodus.[ 1] The likely compiler of the medieval version is Eleazar of Worms, as Sefer Galei Razia, which developed into what we have now as Sefer Raziel, including more writings written by people of various theological opinions.[ 2] According to Jacob Emden, it was compiled by Abraham Abulafia.
It draws heavily on Sefer Yetzirah and Sefer HaRazim "Book of Secrets". There are multiple manuscript versions, containing up to seven tractates. The printed version of Sefer Raziel is divided into five books, some of it in the form of a mystical midrash on Creation. It features an elaborate angelology, magical uses of the zodiac, gematria, names of God, protective spells, and a method of writing magical healing amulets.
