Crobialus or Krobialos (Ancient Greek: Κρωβίαλος) was a town on the Black Sea coast of ancient Paphlagonia, mentioned by Apollonius Rhodius,[1] with Cromna and Cytorus; and Gaius Valerius Flaccus has the same name.[2] Stephanus of Byzantium quotes the verse of Apollonius.[3] We may assume that it was in the neighbourhood of Cromna and Cytorus. Strabo observes of the line in Homer's Iliad "Κρῶμνάν τ᾽ Αἰγιαλόν τε καὶ ὑψηλοὺς Ἐρυθίνους"[4] that some persons write [Κώβιαλον] Error: {{Lang}}: invalid parameter: |3= (help), meaning 'at Cobialus', in place of [Αἰγιαλόν] Error: {{Lang}}: invalid parameter: |3= (help), meaning 'at Aegialus'.[5] Crobialus and Cobialus seem to be the same place. However, Crobialus and Aegialus were distinct.[6]
Its site is unlocated.[6]
