[49] It will suffice for our purpose that there are a number of problems which it is difficult to solve in any other way, which are as a rule solved by these linear demonstrations, such as the method of division, section to infinity, ¹ and the ratio of increase in velocity. From this we may conclude that, if as we shall show in the next book an orator has to speak on every kind of subject, he can under no circumstances dispense with a knowledge of geometry.

[49] illud utique iam proprium ad efficiendum quod intendimus, plurimas quaestiones, quibus difficilior alia ratione explicatio est, ut de ratione dividendi, de sectione in infinitum, de celeritate augenda, linearibus illis probationibus solvi solere; ut, si est oratori (quod proximus demonstrabit liber) de omnibus rebus dicendum, nullo modo sine geometria esse possit orator.

Institutio Oratoria

1. Quintilian is perhaps referring to the measurement of the area of an irregular figure by dividing it into a number of small equal and regular figures the size of which was calculable.
