The geographica open with island perimeters. Of the large islands Sardinia has a circuit of 4,240 stadia (592 miles); Kyrnos, which the locals call Corsica, the same; Crete 4,300; Cyprus 3,000. Of the British islands the greatest, called Albion, has a circuit of 39,000 stadia; Ierne is proportionally larger. The Peloponnese is 4,500 stadia; Rhodes 825; Cos 800; Chios 1,600; Lesbos 1,180; Samos 800. The length of the whole earth from east to west they say is 80,000 stadia.
The whole earth’s greatest circuit is put at 250,000 stadia, its surface at two hundred myriads of myriads, of which our inhabited world is about a fourth. The length of the whole stretch from the Pillars of Heracles to eastern Syria is not much short of 30,000. Marathon is 300 stadia from the city; the Hellespont is a strait seven stadia wide, which Xerxes bridged; Sicily’s circuit is 4,800 stadia (645 miles).
The slot is those leftover measurements, not a missing geographer.
