What is "echinades"

The Echinades (; Greek: per Herodotus, Thucydides, and Strabo, per Homer Echinae (, ) are a group of islands in the Ionian Sea, off the coast of Acarnania, Greece. The archipelago is commonly subdivided into three groups: the Drakoneres in the north, the Modia in the middle and the Ouniades in the south. Administratively, the Echinades form part of two regional units: Ithaca and Cephalonia. Six of the islands, including Oxeia the largest, are owned by Sheikh Hamad bin Khalifa al-Thani, the emir of Qatar, who purchased them for a reported £7.3 million sterling. The Battle of the Echinades in 1427 and the Battle of Lepanto in 1571 were fought at or near the islands.
