Rhithymna or Rithymna (Ancient Greek: Ῥίθυμνα) or Rhithymnia (Ῥιθυμνία), was a town of ancient Crete, Greece, which is mentioned by Ptolemy[1] and Pliny the Elder[2] as the first town on the north coast to the east of Amphimalla, and is spoken of as a Cretan city by Stephanus of Byzantium, in whose text its name is written Rhithymnia; Stephanus gives the city's ethnonyms as Ῥιθυμνιάτης and Ῥιθύμνιος.[3] It is also alluded to by Lycophron (76). Modern Rethymno retains the name of the ancient city, upon whose site it stands. Rhithymna minted coins in antiquity; maritime emblems are found on them.[4] It is believed that Arsinoe is the same town as Rhithymna.[5][6]
