Correct...I'm not sure where he got the atlas from, etc...
Things like "Gades" or "Cadiz" in Spain appear as an island, when it is not an island today.
It sounds to me like these guys found the city "Cephalania".
It would be interesting to compare Strabo, or Ptolemy.
By 450BC, "Ithaca" and "Cephalania" are two different islands, as described in the "Periplus of Pseudo-Skylax".
"34. AKARNANIA. And after Ambrakia is the nation Akarnania, and the first city on this spot
is Argos the Amphilochian, and Anaktorion with a harbour, and outside the Anaktoric gulf the
following cities: Akte and the city Leukas with a harbour: this city stands forth upon the
Leukatas, which is a promontory from afar in the sea*. This city they formerly used to name
Epileukadioi. And Akarnanes having made civil war took out of Corinth one thousand resettlers:
and the re-settlers having killed them hold their territory themselves. And this city is now
an island, having cut off the isthmus with a ditch [Euripos dug through in the isthmus]. And
after these places a city, Phara, and by these places there is an island, Ithaca, with a city and a
harbour. After these places an island, Kephalenia. And I return again onto the mainland, whence
I left. After these places a city, Alyzia, and by this an island, Karnos, and a city, Astakos, with a
harbour, and the river Acheloös, and Oiniadai city: and to these [cities] there is a voyage inland
by the Acheloös. And there are also other cities of Akarnanians in the interior. And the coastal
voyage of Akarnania is of two days*. And Akarnania all has good harbours: and by these places
many islands lie beside, which the Acheloios by silting up is making mainland. The islands are
called Echinades: and they are deserted."
