A discourse was published in 1614, titled 'A True and Wonderful Discourse relating a strange and monstrous Serpent (or Dragon) lately discovered, and yet living, to the great Annoyance and divers Slaughters of both Men and Cattel, by his strong and violent Poison: in Sussex, two Miles from Horsham, in a woode called St Leonard's Forrest, and thirtie miles from London, this present Month of August, 1614. With the true Generation of Serpents'. In this pamphlet the creature is described as: 'nine feete, or rather more, in length, and shaped almost in the forme of an axle-tree of a cart; a quantitie of thickness in the middest, and somewhat smaller at both endes. The former part, which he shootes forth as a necke, is supposed to be about an elle long; with a white ring, as it were, of scales about it. The scales along his backe seem to be blackish, and so much as is discovered under his bellie, appeareth to be red; ...It is likewise discovered to have large feete, but the eye maybe there deceived; for some suppose that serpents have no feete ... [He] rids away (as we call it) as fast as a man can run. He is of countenance very proud, and at the sight or hearing of men or cattel, will raise his neck upright, and seem to listen and looke about, with great arrogancy. There are likewise upon either side of him discovered, two great bunches so big as a large foote-ball, and (as some thinke) will in time grow to wings, but God, I hope, will (to defend the poor people in the neighbourhood) that he shall be destroyed before he grow so fledge.'
The dragon was thought to live on rabbits; although he (or rather the 'venome' he shot forth) killed dogs and people, he did not eat them. It is also interesting that always 'in his track or path [he] left a glutinous and slimie matter ... which is very corrupt and offensive to the scent ...' No one has yet been able to suggest a known animal which fits the description of the St Leonard’s Forest 'dragon.'
