We have described Paphlagonia bordering upon Pontus; and as the Bithynians border upon the Paphlagonians towards the west, we shall endeavour to describe this region also. We shall then set out again from the Bithynians and the Paphlagonians, and describe the parts of the country next to these nations lying towards the south; they extend as far as the Taurus, and are parallel to Pontus and Cappadocia; for some order and division of this kind are suggested by the nature of the places. CHAPTER IV. 1. Bithynia is bounded on the east by the Paphlagonians, Mariandyni, and by some tribes of the Epicteti; on the north by the line of the sea-coast of the Euxine, extending from the mouth of the Sangarius[1205] to the straits at Byzantium and Chalcedon; on the west by the Propontis; on the south by Mysia and Phrygia Epictetus, as it is called, which has the name also of Hellespontic Phrygia. 2. Here upon the mouth of the Pontus is situated Chalcedon, founded by the Megareans,[1206] the village Chrysopolis, and the Chalcedonian temple. In the country a little above the sea-coast is a fountain, Azaritia, (Azaretia?) which breeds small crocodiles. Next follows the coast of the Chalcedonians, the bay of Astacus,[1207] as it is called, which is a part of the Propontis. Here Nicomedia[1208] is situated, bearing the name of one of the Bithynian kings by whom it was founded. Many kings however have taken the same name, as the Ptolemies, on account of the fame of the first person who bore it. On the same bay was Astacus a city founded by Megareans and Athenians; it was afterwards again colonized by Dœdalsus. The bay had its name from the city. It was razed by Lysimachus. The founder of Nicomedia transferred its inhabitants to the latter city.
