place where tlie town of Spiropolis^ formerly stood. The 
Thyni occupy the whole of the coast, the Bithyni the in- 
terior. This is the termination of Asia, and of the 282 
peoples, that are to be found between the Grulf of Lycia^ 
and this spot. We have already^ mentioned the length of 
the Hellespont and Propontis to the Thracian Bosporus as 
bein^ 239 miles ; from Chalcedon to Sigeum, Isidorus makes 
the distance 322-|-. 
CHAP. 44. — THE ISLANDS OF THE PEOPONTIS. 
The islands of the Propontis are, before Cyzicus, Elaphon- 
nesus^, from whence comes the Cyzican marble ; it is also 
known by the names of Neuris and Proconnesus. Next 
come Ophiussa^, Acanthus, Phoebe, Scopelos, Porphyrione, 
Halone^, with a city of that name, Delphacia, Poly dor a, and 
Artaceon, with its city. There is also, opposite to Mco- 
media, Demonnesos^ ; and, beyond Heraclea, and opposite 
to Bithynia, the island of Thynias, by the barbarians called 
Bithynia ; the island of Antiochia : and, at the mouth of 
the Miyndacus, Besbicos^, eighteen miles in circumference ; 
the islands also of Elsea, the two called Ehodussse, and those 
of Erebinthus^, Megale, Chalcitis^^, and Pityodes^\ 
I Called Phinopolis in most of the editions. It is very doubtful 
whether this passage ought not to be translated, " At a distance thence of 
eight miles and three-quarters is the first entrance to this strait, at the 
spot," &c. We have, however, adopted the rendering of Holland, Ajas- 
son, and Littre. ^ Mentioned in C. 28 of the present Eook. 
3 In B. iv. c. 24 ^ Qr "Deer Island." 
^ Now Afzia, according to D'Anville. 
^ There is still an island m the Sea of Marmora known by the name 
Alon, which is separated from the north-western extremity of the Penin- 
sula of Cyzicus by a narrow channel. 
7 Hesychius says, that there were two islands near Byzantium called 
by the common name of Demonnesi, but severally having the names of 
Chalcitis and Pityusa. Pliny, on the other hand, places Demonnesus 
opposite to Nicomecha, and at the same time mentions Chalcitis and 
Pityodes (^probably the same as Pityusa) as distinct places. D'Anville 
calls Demonnesus " The Isle of Prmces." 
8 The position assigned to this island by Pliny and Strabo corresponds 
with that of Kalohmno, a small island ten miles north of the mouth of 
the Rhyndacus. ^ Now called Prota, according to Parisot. 
1^ So called from its copper-mines ; now called Khalki, or Karki, 
II Now called Prinkipo, east of Khalki.
