21. Plinius Hist. Nat., II, 112:

Pars nostra terrarum, de qua memoro, ambienti oceano velut innatans longissime ab ortu ad occasum patet, hoc est ab India ad Herculis columnas Gadibus sacratas LXXXV. LXVIII mill. pass., ut Artemidoro auctori placet, ut vero Isidoro, XCVIII. et XVIII. M.

22. Id. II, 112:

Latitudo autem terrae a meridiano situ ad septentriones dimidio fere minor colligitur XLIIII. LXXXX milia. Sequuntur partes hujus mensurae quae pertinent a meridie ultima usque ad ostum Tanais (V fr. Artemid.) Dein Plinius pergit: Ab ostio Tanais nihil modi quam diligentissimi auctores fecere; Artemidorus ulteriora incomperta existumavit, quum circa Tanaim Sarmatarum gentis degere fateretur ad septentriones versus; Isidorus adjecit duodeciens centena millia quinquaginta usque ad Thulen, quae conjectura divinationes est.

23. Id. V. 9:

21. (Pliny, Natural History, II, 112.)

Our part of the earth, of which I propose to give an account, floating as it were in the ocean which surrounds it, 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, according to the statement of Artemidorus, or according to that of Isidore, 9818 miles.

22. (Ibid., II, 112.)

The breadth of the earth from south to north, is commonly supposed to be about one-half only of its length, viz., 4490 miles; (then follow parts of these measurements from the southern extremities to the mouth of Tanais). Beyond the Tanais the most diligent authors have not been able to obtain any accurate measurement. Artemidorus supposes that everything beyond is undiscovered, since he confesses that, about the Tanais, the tribes of the Sarmatae dwell, who extend toward the North Pole. Isidore adds 1250 miles, as the distance to Thule; but this is mere conjecture.

23. (Ibid., V, 9.)

The whole distance (of Asia) to the Tanais, including Egypt, is, according to Artemidorus and Isidore, 6375 miles.

24. (Ibid., IV, 37.)

Artemidorus and Isidore have given the length of it (Europe) from the Tanais to Gades, as 8214 miles.

25. (Ibid., V, 6.)

Isidore speaks of the distance from Tingi to Canopus as being 3599 miles. Artemidorus makes this last distance forty miles less than Isidore.

26. (Ibid. V, 43.)

From Chalcedon to Sigeum, Isidore makes the distance 322 ½ miles.

27. (Ibid., V, 35.)

Timosthenes states that the circumference of this island [Cyprus] is 427 miles, Isidore 375.

28. (Ibid., V, 36.)

The fairest of them all is the free island of Rhodes, 125, or if we would rather believe Isidore, 103 miles in circumference . . . . . . It is distant from Alexandria in Egypt, according to Isidore, 583 miles; but according to Eratosthenes, 469. Mucianus says that its distance from Cyprus is 166.

29. (Ibid., V, 37.)

The coast of Ionia has Samos, a free island, eighty-seven miles in circumference, or, according to Isidore, 100.

30. (Ibid., V, 38.)

The free island of Chios . . . . . . is 125 miles in circumference, according to the ancient writers; Isidore, however, makes it nine more.

31. (Ibid., V, 39.)

The circumference of the whole island [Lesbos] is, according to Isidore, 168 miles; but the older writers say 195.

32. (Ibid., IV, 5.)

The Peloponnesus . . . . . . situated between two seas, the Aegean and the Ionian, is in shape like the leaf of a plane-tree, in consequence of the angular indentations made in its shores. According to Isidore, it is 563 miles in circumference; and nearly as much again, allowing for the coast-line on the shores of its bays.

33. (Ibid., IV, 30.)

This island [Britain] is distant from Gesoriacum, on the coast of the nation of the Morini, at the spot where the passage across is shortest, fifty miles. Pytheas and Isidore say that its circumference is 4875 miles.
