The Touchstone of Complexions was actually written in 1576 by the Dutch physician Lemnius Levinus. It was later translated from Dutch to English by Thomas Newton and repunlished in editions like this one from 1633.
The fact that an edition was still printed 60 years later meant that his ideas remained relevant for a long period of time. This, along with other literature of the humors, set a precedent for later works like Burton's The Anatomy of Melancholy.
