 One initially plausible stimulus for the medieval discussions would appear to be the Epistle to Titus 1:12: “One of themselves, even a prophet of their own, said, The Cretians [= Cretans] are always liars, evil beasts, slow bellies”. The Cretan in question is traditionally said to have been the sixth-century BCE thinker Epimenides. For this reason, the Liar Paradox is nowadays sometimes referred to as the “Epimenides”. Yet, blatant as the paradox is here, and authoritative as the Epistle was taken to be, not a single medieval author is known to have discussed or even acknowledged the logical and semantic problems this text poses. When medieval authors discuss the passage at all, for instance in Scriptural commentaries, they seem to be concerned only with why St. Paul should be quoting pagan  sources.[5]  It is not known who was the first to link this text with the Liar Paradox.
