The Heptameron, or Magical Elements, is a 15th Century manual of ritual magic detailing the angels summoned on each day of the week, their unique sigils, ruling planets, and astrological powers. Attributed to the Italian philosopher Peter de Abano, the Heptameron is an occult classic. This new edition is based primarily upon the 1665 translation by Robert Turner housed at the British Museum. Featuring new translations of the Latin and extensive annotations throughout the text, this handsome book provides a guided tour through the beliefs and practices of Renaissance Europe's ceremonial magicians.
