a distance of 555 miles ; Agrippa, however, increases tlie 
length by sixty miles. The distance thence to Macron Tichos, 
or the Long Wall, previously mentioned, is 150 miles ; and, 
from it to the extremity of the Chersonesu.s, 126. 
On leaving the Bosporus we come to the Grulf of Cas- 
thenes\ and two harbours, the one called the Old Men*s 
Haven, and the other the Women's Haven. Next comes 
the promontory of Chrysoceras^, upon which is the town of 
Eyzantium^, a free state, formerly called Lygos, distant from 
Dyrrhachium 711 miles, — so great being the space of land 
that intervenes between the Adriatic Sea and the Propontis. 
We next come to the rivers Bathynias and Pydaras^, or 
Athyras, and the towns of Selymbria^ and Perinthus^, which 
join the mainland by a neck only 200 feet in width. In the 
interior are Bizya'', a citadel of the kings of Thrace, and hated 
by the swallows, in consequence of the sacrilegious crime 
of Tereus^ ; the district called Cgenica^, and the colony of 
Flaviopclis, where formerly stood a town called C^la. Then, 
at a distance of fifty miles from Bizya, we come to the colony 
of Apros, distant from Philippi 180 miles. Upon the coast 
is the river Erginus^^; here formerly stood the town of 
Granos^^ ; and Lysimachia^^ in the Chersonesus is being now 
gradually deserted. 
At this spot there is another isthmus^', similar in name 
to the other and of about equal width ; and, in a manner 
^ Between G-alata and Fanar, according to Brotier. 
2 Or Grolden Horn ; still known by that name. 
3 The site of the present Constantinople. 
4 These rivers do not appear to have been identified. 
5 The present SiUvri occupies its site. 
6 An important town of Thrace. Eski Erekli stands on its site, 
7 'Now Vizia, or Yiza. 
^ He alludes to the poetical story of Tereus, king of Thrace, Progne, 
and Philomela. Aldrovandus suggests that the real cause of the absence 
of the swallow is the great prevalence here of northern winds, to which 
they have an aversion. 
^ So called probably from the Thracian tribe of the Csenici, or Cseni. 
Now called Erkene, a tributary of the Hebrus. 
All that is known of it is, that it is mentioned as a fortress on the 
Propontis. ^2 Hexamila now occupies its site. 
12 The isthmus or neck of the Peninsula of GraUipoli, or the Dardanelles. 
1^ That of Corinth. They are both about five miles wide at the nar- 
rowest part.
