Abramelin
Abramelin also spelt Abra-Melin, was an Egyptian Philosopher and learned student of the Occult, who passed on the knowledge for contacting the Holy Guardian Angel to Abraham Von Worms in 1392.

This book is known as the "Sacred Magic of Abramelin the Mage," and has been in circulation since the 16th century, first published in 1608 in Germany.

The system of magic from this book regained popularity in the 19th and 20th centuries partly due to Samuel Liddell MacGregor Mathers' translation, "The Book of the Sacred Magic of Abramelin the Mage;" and partly to its importance within the Hermetic Order of the Golden Dawn, and later within the system of Thelema and the magical secret society the A.'.A.'. (created in 1904 by Aleister Crowley).

Abramelin is regarded as an important figure in the Occult world from history, standing beside contemporaries such as Dr. John Dee and Nicholas Flamel.
