Sepher Raziel (also called Liber Salomonis) is not the same as the Hebrew Sepher Raziel ha-Melakh.
It is a full grimoire in the Solomonic tradition from a 1564 century English manuscript, derived from Latin sources.
As such it is one of the earliest grimoires produced in this series. It begins with directions for making the parchment, pen and ink of Art, required to write the names. It contains seven separate Treatises: 1 - Liber Clavis which is concerned with astrology and its correct use in magic, something long forgotten by modern astrologers, with the precise interactions between planets, Signs and Houses; 2 - The Ala outlines in four sections the magical virtues of stones, herbs and beasts, and words; 3 - The Tractatus Thymiamatus explains why incense is essential to magical operations, and the effect of various incenses on the spirits, with a list of the key perfumes and suffumigations.
