De Dualitate. cap. 117.
IF one be put to one, then commeth twaine, & that number is after one first principall, & well of numbers. And holdeth the secondarye place, as Isidore sayeth. And this number is called Page [unnumbered]Binarius, and is called Infamu among some men, for by the number of twaine we be departed from one. And so this number is taken of diuision and depar∣ting. But Aul. in. 6. Musice saith, that if this number be to blame, for he pas∣seth first from one, then he is praising, for he commeth of one, and migheth or is first before the number of three.
