Hibernia Hibernia is the Classical Latin name for the island of Ireland. The name "Hibernia" was taken from Greek geographical accounts. During his exploration of northwest Europe (c. 320 BC), Pytheas of Massilia called the island "Iérnē" (written Ἰέρνη ). In his book "Geographia" (c. 150 AD), Claudius Ptolemaeus ("Ptolemy") called the island "Iouerníā" (written Ἰουερνία , where "ου"/"ou" stands for "w"). The Roman historian Tacitus, in his book "Agricola" (c. 98 AD), uses the name Hibernia.
