Italian Philosopher Giordano Bruno ("the Nolan") was one of the most original and colorful thinkers of the Renaissance. The Inquisition considered him a dangerous heretic, and had him burned at the stake in 1600.
Bruno became a noted expert in the art of memory while still a Dominican monk. He repeatedly demonstrated his memory techniques, including to Pope Pius V. Bruno carried the traditional mnemonic training well beyond the Dominican traditions.
This is Bruno's first book on memory, and presents a rich system which integrates mnemonics, psychology (ala Ficino), and hermetic magic. This work is dealt with at some length by Frances A. Yates in her Giordano Bruno and the Hermetic Tradition (1964).
An early work by Bruno on the art of memory with strong magical elements. It is written in the form of a dialogue between the great sorceress Circe and her assistant or apprentice Moeris.
Another major work of Bruno's, almost impossible to find, dealing with the philosophy of love and love as a means of mystical ascent.
One of the very few of Bruno's books to deal explicitly with magic. It remained unpublished until Tocco's edition of 1891. For a translation, see Cause, Principle, and Unity, ed. Blackwell et al.
By "mathematical magic" Bruno means magical practices that use characters, seals, and figures.
This is Bruno's other great book on magic, dealing with "bonding in general." Couliano characterizes it as "one of those little-known works whose importance in the history of ideas far outstrips that of more famous ones." (Eros and Magic in the Renaissance, p. 89.) It explains how the masses can be manipulated with psychological and magical bonds, and how one can escape these snares.
