which I ſuppoſe to be the one called (probably from that circumſtance) Pſeudoiizoma, by Pliny and Ptolemy.
Diſtance according to Arrowſmith's chart,
| From the firſt mouth Bogaii) to the ſecond, called Sulina Bogaii, | 16′ | |
| From the ſecond to the third, Ghiurcheri, | 17′ | |
| From the third to the fourth, Vizi Bogaſi, | 7′ | 30″ |
| 40′ | 30″ | |
| Equal to 47 miles, or about 409 ſtadia. | ||
Laurie and Whittle's chart varies but little, and theſe calculations are a kind of mean between thoſe of Arrian and of Ptolemy. It is poſſible that the river may have changed its courſe, and ſome of the mouths be blocked up, or choaked with ſoil and ſand, brought down by the current.
The fifth mouth of Arrian is the ſame with the iixth of Pliny and of Ptolemy. Strabo makes ſeven mouths, and about 300 ſtadia, or about 37½ Greek miles, or 34¼ Engliſh miles from the firſt to the ſeventh. He reckons the order of them in an oppoſite direction to Arrian, as he counts the moſt ſoutherly to be the firſt.
From the fifth mouth to the city of Iſtria 500 ſtadia. Strabo ſays, that from Pence to Iſtria is 500 ſtadia. D'Anville makes it to be 400 ſtadia only, which is nearly the diſtance which a place called Viſtar, or Viſtwar, meaſures on modern maps. Perhaps this may be the ſite of the ancient city of Iſtria, or Iſiropolis, although the diſtances do not exactly agree.
