GID: 1_94
Year: 1650
Description: Another image similar to no. 93, from Descartes's Compendium musicae. This time the notes of the scale are labelled with musical pitch names, from F upwards. In this different form of the scale from image 93 the 'schism' is put in a different place. The sizes of some intervals are strikingly inaccurate, despite the evident intention to make their angles correspond to their logarithmic sizes.
