Allegory of music. 16th-century woodcut showing Lady Music (centre) as part of an allegory on music. At upper left is a composer (poeta). At upper right is Tubal, biblical blacksmith. At lower right is 5th-century BC Ancient Greek philosopher Pythagoras, whose experiments on musical harmonics were inspired by hearing the blacksmith's hammer striking the anvil. At centre is a conductor. Musicians (left) are playing an organ, a harp, a lute and a recorder. Artwork from 'Aepitoma omnis phylosophiae' (1504) by German author Georg Reisch (c.1467-1525). This work is better known as 'Margarita philosophica' and was first published in 1503.
