Linquo coax ranis are the first words of a two-line poem in internally rhymed hexameters by Serlo of Wilton. The complete text is: Linquo coax ranis, cras corvis, vanaque vanis;Ad logicam pergo que mortis non timet ergo.I leave croaking to frogs, crowing to crows, and vanity to the vain;I now go to the logic that does not fear the "therefore" of death. The legend was investigated by the French novelist and philologist Marcel Schwob in his pamphlet La légende de Serlon de Wilton (Paris, 1899).
