Pietro d'Abano was a philosopher, astrologer, and physician active in the late thirteenth and early fourteenth centuries. He is best known for his medical treatises and a magical text called the Heptameron. Scholars view him as a bridge between ancient knowledge and later European science.

D'Abano wrote extensively on medicine and astrology. He reconciled contradictions between Aristotle and contemporary medical knowledge. He also authored the Heptameron, a book of rituals for conjuring angels. These rituals were tied to the days of the week. His medical methods focused on physical causes rather than spiritual ones.
