 In the 13th century the category of "reptile" was recognized in Europe as consisting of a miscellany of egg-laying creatures, including "snakes, various fantastic monsters, lizards, assorted amphibians, and worms", as recorded by Vincent of Beauvais in his "Mirror of Nature".In the 18th century, the reptiles were, from the outset of classification, grouped with the amphibians.Linnaeus, working from species-poor Sweden, where the common adder and grass snake are often found hunting in water, included all reptiles and amphibians in class "III – Amphibia" in his "Systema Naturæ".
