Ceramus or Keramos () is a city on the north coast of the Ceramic Gulf—named after this city—in ancient Caria, in southwest Asia Minor; its ruins can be found outside the modern village of ÃÂren, MuÃÂla Province, Turkey.
Ceramus, initially subjected to Stratonicea, afterwards autonomous, was a member of the Athenian League and was one of the chief cities of the Chrysaorian League (Bulletin de corresp. hellén., IX, 468). It probably had a temple of Zeus Chrysaoreus. In Roman times, it coined its own money.
Polites () of Ceramus was a famous runner who won three different races in the same day at the Olympia.
Ceramus is mentioned in the Notitiae Episcopatuum until the 12th or 13th century as a bishopric suffragan to Aphrodisias, or Stauropolis. Three bishops are known: Spudasius (ãÃÂÿàôìÃÂùÿÃÂ), who attended the First Council of Ephesus in 431; Maurianus (ÃÂñàÃÂùñýÃÂÃÂ), who attended the Council of Nicaea in 787; and Symeon (ãàüõÃÂý), who attended the council in Constantinople that reinstated Photius in 879.
Ceramus is included in the Catholic Church's list of titular sees.
