Perspice nunc tenuem visu rem, pondere magnam
et tantum Graio signari nomine passam,
dodecatemoria, in titulo signantia causas.
nam, cum tricenas per partes sidera constent,
rursus bis senis numerus diducitur omnis;
ipsa igitur ratio binas in partibus esse
dimidiasque docet partes.
‘Pray examine now a matter trivial in appearance, yet one of great moment, which does not permit description of itself save by a Greek word. I speak of the dodecatemories, of which the name proclaims the principle. The signs each consist of thirty degrees, and every total is further divided by twice six; the calculation therefore shows that in each division there are two and a half degrees.’
