 Consilia

Consilia (plural of "consilium", "advice") is a genre of book, originating in medieval era plagues, where practical advice is given on a medical or other philosophical subject.The format was originated by the Florentine doctor of medicine Taddeo Alderotti, under the pressures for down-to-earth advice, based on experiential observations, in treating the Black Death that decimated Italy in 1348 and recurred at generational intervals for the following centuries.
