Abstract

Gell. NA 3.10.13 citing Varro's Hebdomades uel de imaginibus, reports: Venas etiam in hominibus, uel potius arterias, medicos musicos dicere ait numero moueri septenario, quod ipsi appellant τν δι τεσσρων συμφωναν, quae fit in collatione quaternarii et ternarii numeri. He also states that doctors who make use of music theory declare that the veins, or rather arteries, in human beings move in accordance with the number seven; they call this motion ‘the consonance of the fourth’, which is produced by the proportional relation of the numbers four and three
