The Heptameron and Its Attribution to Peter of Abano

Record summary

The Heptameron is a concise Latin ritual magic text organized around planetary days, hours, angels, circles, and conjurations. It was traditionally linked to the physician and astrologer Pietro d’Abano, although the attribution and textual history are uncertain. The lead matters for studying how medieval learned astrology, angelology, and ritual manuals were assembled and later marketed under prestigious names. Researchers should distinguish manuscript witnesses, early printed editions, and modern occult compilations, since titles and contents vary and the text’s alleged medieval authorship is not secure.
