Rabelais (1490–1553), in his Gargantua and Pantagruel, incorporates into his fantastic and satirical novel contemporary views and personal attitudes on a large variety of subjects—religious and cosmological, literary, metaphysical, and theological. Among the topics and discussions propounded by some of his odd characters is the problem of amatory stimuli:

When I say, quoth Rondibilis, that wine abateth lust, my meaning is, wine immoderately taken; for by intemperance proceeding from the excessive drinking of strong liquor, there is brought upon the body of such a swill-down bouser, a chilliness in the blood, a slackening in the sinews, a dissipation of the generative seed, a numbness and hebetation of the senses, with a perversive wryness and convulsion of the muscles; all of which are great lets and impediments to the act of generation. Hence it is, that Bacchus, the god of bibbers, tipplers, and drunkards, is most commonly painted beardless, and clad in a woman’s habit, as a person altogether effeminate, or like a libbed eunuch. Wine, nevertheless, taken moderately, worketh quite contrary effects, as is implied by the old proverb, which saith,—That Venus takes cold, when not accompanied with Ceres and Bacchus.

On another point in erotic investigations, Rabelais continues:

The fervency of Lust is abated by certain drugs, plants, herbs, and roots, which make the taker cold, maleficiated, unfit for, and unable to perform the act of generation; as hath been often experimented in the water-lily, Heraclea, Agnus Castus, willow-twigs, hemp-stalks, wood-bine, honey-suckle, tamarisk, chaste-tree, mandrake, bennet, keck-bugloss, the skin of a hippopotamus, and many other such, which, by convenient doses proportioned to the peccant humor and constitution of the patient, being duly and seasonably received within the body, what by their elementary virtues on the one side, and peculiar properties on the other,—do either benumb, mortify, and beclumpse with cold the prolific semence, or scatter and disperse the spirits, which ought to have gone along with, and conducted sperm to the places destinated and appointed for its reception,—or lastly, shut up, stop, and obstruct the ways, passages, and conduits through which the seed should have been expelled, evacuated, and ejected. We have nevertheless of those ingredients, which, being of a contrary operation, heat the blood, bend the nerves, unite the spirits, quicken the senses, strengthen the muscles, and thereby rouse up, provoke, excite, and enable a man to the vigorous accomplishment of the feat of amorous dalliance.

Obstructions to such dalliance are now discussed:

The ardor of lechery is very much subdued and check’d by frequent labor and continual toiling. For by painful exercises and laborious working, so great a dissolution is brought upon the whole body, that the blood, which runneth alongst the channels of the veins thereof, for the nourishment and alimentation of each of its members, hath 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 land.
