Ars Notoria (The Notory Art of Solomon)

Ars Notoria, also known as The Notory Art of Solomon, is a medieval grimoire containing a set of prayers and invocations to secure the favor of the Christian God.

Its prayers, sacred names, diagrams, and rituals are intended to help the practitioner improve memory, eloquence, and mastery of academic subjects by seeking knowledge through divine or angelic revelation.

The work is traditionally attributed to Solomon, but its surviving Latin manuscript tradition dates from the Middle Ages.

A version of Ars Notoria was later included as the fifth part of some editions of the Lesser Key of Solomon. Unlike its spirit-conjuration sections, this text centers on prayers for intellectual gifts.
