 One medieval application of wine was the use of snake-stones (banded agate resembling the figural rings on a snake) dissolved in wine as a remedy for snake bites, which shows an early understanding of the effects of alcohol on the central nervous system in such situations.Jofroi of Waterford, a 13th-century Dominican, wrote a catalogue of all the known wines and ales of Europe, describing them with great relish and recommending them to academics and counsellors.Rashi, a medieval French rabbi called the "father" of all subsequent commentaries on the Talmud and the Tanakh, earned his living as a vintner.
