Jordan

wiktionary
From Latin jurdanus, unattested outside of England and of uncertain etymology. Usually derived from a clipped form of Jordan bottle, supposedly a bottle of curative water brought back from the River Jordan by Crusaders and pilgrims to the Holy Land, [1] but this seems unsupported in its actual attestations. Its use for chamber pots may derive from the alchemical device having been used to hold urine. [2]
