STRUTHIUS, Josephus (Józef Struś)
Sphygmicae artis iam mille ducentos annos perditae et desideratae libri V.Basel: Johannes Oporinus, 1555.
Considered the most significant work on the pulse between Galen and Harvey. The work includes what is probably the earliest graphic representation of the pulse. Struthius provided a useful mnemonic of the five simple pulses in the form of a hand (on p. 116). Digital facsimile of the Venice,1573 edition from Google Books at this link.
