V.] ACTAE OR PROJECTING TRACTS. 83 an idea of the conformation of that continent which is peculiar to himself, by dividing it into Actae, or tracts of land of a somewhat peninsular character. After noticing or Projecting the four races which occupy the belt of country Tracts* that intervenes between the southern sea on the hither side of India and the Euxine—the Persians, the Medes, the Saspires and the Colchians—he says that the land to the west of this may be regarded as forming two separate areas. The northernmost of these, starting from a line drawn through the Phasis and the gulf of Issus, is bounded on the north by the Pontus and the Helles- pont up to Sigeium, and on the south by the coast as far as the Triopian promontory in Caria: it corresponds therefore nearly to Asia Minor. The southern area, on the other hand, embraces Persia, Assyria, and Arabia on the side towards the Erythraean sea, and Phoenicia, Palestine, and Egypt in the direction of the Mediterranean. Libya, notwithstanding the width to which it spreads on the further side of Egypt, he regards as an appendage to the second of these Actae1. It is not altogether easy to divine the object which the historian had in view in this grouping of countries, but it reveals to us the imperfection of his knowledge of the relative size of these districts, and it suggests also, what was undoubtedly the case, that he greatly underrated the size both of Asia and of Africa. He was in ignorance, too, of the southward extension of both those continents, for he does not include in his survey the peninsula of Hindostan—an omission which continued to prevail until long after his time—and he believed that the African coast began to trend due west at no great distance from the mouth of the Red Sea. -7 As geography is a subject not systematically introduced into Herodotus' work, but only as subordinate to history, Central and except so far as he indulges in digressions on the Western countries which are noticed in his narrative, we Europe' cannot be surprised if his description of the centre and west of Europe is scanty as compared with that of Asia, since those regions were unconnected with the struggle between Greece and Persia, which it was his purpose to commemorate.
