In ancient Roman religion, Mens, also known as Mens Bona (Latin for "Good Mind"), was the personification of thought, consciousness and the mind, and also of "right-thinking". The founding (dies natalis) of her temple in Rome was celebrated on June 8.[2][3] A temple on the Capitoline Hill in Rome was vowed to Mens in 217 BC on advice from the Sibylline Books, after the defeat of Lake Trasimene,[4] and was dedicated in 215 BC.
