COMMENTARIVS.

QVARE quadratum b d magis excedit quadratum
Af q, quàm b c quadratum:
& idcirco linea f q minor eſt,
quàm b c:
itemq; f minor quam b r. ] _Quoniani exceſſus, quo_
_quadratum b d excedit quadratum b c ad quadratum b d minorem_
_proportionem habet, quàm exceſſus, quo quadratum b d excedit qua_
_dratum f q, ad idem quadratum:
erit ex octaua quinti exceſſus, quo_
_quadratum b d excedit quadratum b c, minor quàm exceſſus, quo ex_
_cedit quadratum f q.
ergo quadratum f q minus est quadrato b c: &_
_propterea linea f q minor linea b c.
Sed f q ad f eandem proportionẽ_
_habet, quam b c ad b r;
utraque enim utriuſque ſeſquialtera est. cum_
14. quinti_igitur f q ſit minor b c, &
f ipſa b r minor erit_.
Et propterea k r ad ſ y maiorem habet, quàm dimidium
Bipſius k r ad ψ b.
] _Est enim k r ad ſ y, ut quadratum p s ad qua_
_dratum ſ y:
& dimidium lineæ K r ad lineam ψ b, ut quadratum e ψ_
_ad quadratum ψ b_.

Et p h maior, quàm f. ] _Nam p h eſt æqualis ſ ω, & r ψ_
