Fit quoque ut ipsius plagae vis excitet ignem, frigida cum venti pepulit vis missa sine igni, nimirum quia, cum vementi perculit ictu, confluere ex ipso possunt elementa vaporis et simul ex illa quae tum res excipit ictum; ut, lapidem ferro cum caedimus, evolat ignis, nec, quod frigida vis ferrist, hoc setius illi semina concurrunt calidi fulgoris ad ictum.
It may be also that the very force of the blow produces fire, when a force of wind, sped forth cold without fire, has struck; doubtless because, when it has smitten with a violent blow, elements of heat may flow together from the wind itself and at the same time from that thing which then receives the blow; just as, when we strike stone with iron, out flies fire, like flint nor do the seeds of hot fire any the less run together at the blow because iron is a cold thing.
