Raymond Lull (1232-1315), Ars
demonstrativa et ars brevis .
(200 pp.)
Scope: Bound Auto ms. Two colophons, one on K6 (calendris februaris
1516) and one on M4 (February 10, 1516). Memory wheels, text
figures on memory and mnemonics. Lull was born in Mallorca and was
one of the most prolific writers of his time. He composed his
texts in Arabic, Catalan, and Latin. The Ars
demonstrativa (1282-1285) is a simplified version of his
elaborate ideas on Art; it details a system he devised to be used
both as a logic and as a metaphysic. He was unique in ascribing
letters instead of numbers to the symbolic elements in his
syllogistic systems and for combining these with geometric
figures. His work is based on the numerology of the 7 planets and
the 12 signs of the Zodiac, divine symbols that influenced the
elemental patterns of nature. The Ars
brevis (1308) is a lesser, philosophical work. Lull was
influenced by medieval Platonism and the Cabala, and in turn
influenced the work of Giordorna Bruno and Pasqual. The Ars brevis was first published in Raymundi Lullii e Opera, 1609, Argentorati,
Lazari Zetzneri, and the Ars
demonstrativa was first published in Opera Omnia, Mainz, 1721-1742, as Vols. III
and IV.
