Only an approximate estimate of the number of Bacon's works can be given even now, although an infinite amount of time and labor has been spent in collecting them. His great work is the Opus ma jus, "the Encyclopaedia and the Organum of the Thirteenth Century." A partial list of some of his other works is the following: Speculum alchemio, 1541 (trans, into English); De mirabili potestate artis et naturo, 1542 (trans, into English, 1659); Libellus de retardants se-nectutis accidentibus, 1590 (trans, as "The Cure of Old. Age," 1683); and Sanioris medicino Magistri d. Rogeri Baconis Anglici de arte chymio scripta, 1603. 248
