The six northern islands are off the west coast of Greece, in the Ionian Sea. The seventh island, Kythira, is off the southern tip of the Peloponnesus, the southern part of the Greek mainland.
The islands themselves are known by a rather confusing variety of names. During the centuries of rule by Venice, they acquired Venetian names, by which some of them are still known in English (and in Italian). Kerkyra was known as Corfù, Ithaki as Val di Compare, Kythera as Cerigo, Lefkada as Santa Maura and Zakynthos as Zante.
A variety of spellings are used for the Greek names of the islands, particularly in historical writing. Kefallonia is often spelled as Cephallenia or Cephalonia, Ithaki as Ithaca, Kerkyra as Corcyra, Kythera as Cythera, Lefkada as Leucas or Leucada and Zakynthos as Zacynthus or Zante. Older or variant Greek forms are sometimes also used: Kefallinia for Kefallonia and Paxos or Paxoi for Paxi.
