Our part of the earth, of which I propose to give an account, floating as it were in the ocean which surrounds it (as I have mentioned above[737]), stretches out to the greatest extent from east to west, viz. from India to the Pillars consecrated to Hercules at Gades, being a distance of 8568 miles[738], according to the statement of Artemidorus[739], or according to that of Isidorus[740], 9818 miles. Artemidorus adds to this 491 miles, from Gades, going round by the Sacred Promontory, to the promontory of Artabrum[741], which is the most projecting part of Spain. This measurement may be taken in two directions. From the Ganges, at its mouth, where it discharges itself into the Eastern ocean, passing through India and Parthyene, to Myriandrus[742], a city of Syria, in the bay of Issus, is a distance of 5215 miles[743]. Thence, going directly by sea, by the island of Cyprus, Patara in Lycia, Rhodes, and Astypalæa, islands in the Carpathian sea, by Tænarum in Laconia, Lilybæum in Sicily and Calaris in Sardinia, is 2103 miles. Thence to Glades is 1250 miles, making the whole distance from the Eastern ocean 8568 miles[744]. The other way, which is more certain, is chiefly by land. From the Ganges to the Euphrates is 5169 miles; thence to Mazaca, a town in Cappadocia, is 319 miles; thence, through Phrygia and Caria, to Ephesus is 415 miles; from Ephesus, across the Ægean sea to Delos, is 200 miles; to the Isthmus is 212-1/2 miles; thence, first by land and afterwards by the sea of Lechæum and the gulf of Corinth, to Patræ in Peloponnesus, 90 miles; to the promontory of Leucate 87-1/2 miles; as much more to Corcyra; to the Acroceraunian mountains 132-1/2, to Brundisium 87-1/2, and to Rome 360 miles. To the Alps, at the village of Scingomagum[745], is 519 miles; through Gaul to Illiberis at the Pyrenees, 927; to the ocean and the coast of Spain, 331 miles; across the passage of Gades 7-1/2 miles; which distances, according to the estimate of Artemidorus, make altogether 8945 miles.
