[112] _Exploration des ruines d' Antinoe_, by A.C. Gayet (Annales du Musée Guimet, xxvi, Paris, 1897); _Grundzüge der Papyruskunde,_ Wilcken, i, pp. 49, 50. Professor A.S. Hunt refers me to the following papyri:--Reinach, 49. 11; Oxyrhynchus, 1110. 9-10 and note there; Brit. Mus. 1164 (c) 12. The numeration of the divisions of the town by letters was borrowed from Alexandria, where the five parts of the city were known as A, B, C, D, E. For plans see the Napoleonic _Description d'Égypte_ iv (Paris, 1817), plate 53, and E. Jomard, _Antiquités d'Égypte_ (1818), chap. xv. [Illustration: FIG. 34. BOSTRA. (After Baedeker.)] Another instance may be found still further east, in the land beyond Jordan, at the capital of the Haurân, Bosrâ, anciently Bostra. Little has been achieved in the way of exploration of this site beyond studies of the stately ruins of theatres, palaces, temples, triumphal arches, aqueducts. Little can therefore be said as to the date of its ground-plan. But it was rectangular in outline, or nearly so; and its streets crossed at right angles and enclosed rectangular insulae.[113] The place owes all its greatness to Rome. During the second century it was the fortress of the Legio III Cyrenaica, which guarded this part of the eastern Roman frontier. About A.D. 225 it became a 'colonia,' and perhaps we should date from this the town-plan just described (fig. 34). [113] Baedeker, _Palestine and Syria_ (1906), p. 162. This rectangular planning remained long in use in the Eastern Empire. When in A.D. 705 (as it seems) the town of Chersonnesus in the Crimea was rebuilt after a total destruction, it was rebuilt on a symmetrical plan of oblong 'insulae' (25-30 by 60-70 yds. area). Its streets were mean and narrow. But their plan at least was apparently more regular than that of their predecessors.[114] [114] Minns, _Greeks and Scythians_, pp. 493, 508, and references there given. CHAPTER X ROMAN BUILDING-LAWS
