The ancient Greek philosopher Aristotle wrote about many things. He did not, however, write any of the items attributed to him in this section. This collection includes texts that purported to be by Aristotle but were in fact not. Aristotle was a victim of his success, and his name lent credibility and authority to the text associated with it, causing forgeries to proliferate for centuries. From the Italian ABC of misogynistic sayings to the Problems , pseudo-Aristotle was everywhere. The widely popular Secret of Secrets has a particularly rich history. This collection of texts emerged at different times in the medieval Arabic manuscript tradition and circulated as a collection in many languages during the Middle Ages and Renaissance. Purportedly a letter from Aristotle to his most famous student, Alexander the Great, the content ranged from advice to rulers to magic and from ethics to astrology. Renaissance humanists were acutely aware of the quandary posed by texts misattributed to Aristotle. In the imposing Latin work shown here, the committed Platonist professor Francesco Patrizi called into doubt the authenticity of many Aristotelian writings. Ironically, modern scholars now treat as spurious the four texts that Patrizi determined to be authentic.
