"_Thirdly_. The ardour of lechery is very much subdued and mated by frequent labour and continual toiling. For by painful exercises and laborous working so great a dissolution is brought upon the whole body, that the blood which runneth alongst the channels of the vein thereof for the nourishment and alimentation of each of its members, had neither time, leisure, nor power to afford the seminal resudation or superfluity of the third concoction, which nature most carefully reserves for the conservation of the individual, whose preservation she more heedfully regardeth than the propagation of the species and the multiplication of human kind. Whence it is that Diana is said to be chaste, because she is never idle, but always busied about hunting. For the same reason was a camp, or leaguer of old called--Castrum,[222] as if they would have said--Castum; because the soldiers, wrestlers, runners, throwers of the bar, and other such like athletic champions, as are usually seen in a military circumvallation, do incessantly travail and turmoil, and are in a perpetual stir and agitation. To this purpose, also, Hippocrates writeth in his book, _De Aere, Aqua et Locis_:--That in his time there were people in Scythia as impotent as eunuchs in the discharge of a venerean exploit; because that, without any cessation, pause or respite, they were never from off horseback, or otherwise, assiduously employed in some troublesome and molesting drudgery.
