Cosmas expressly states that he was not in Ceylon himself, but that he derived his information respecting it and its trade from Sopatrus, a Greek, who died about the beginning of the sixth century. This, as Dr. Vincent observes, is a date of some importance: for it proves that the trade opened by the Romans from Egypt to India direct, continued upon the same footing from the reign of Claudius and the discovery of Hippalus, down to A.D. 500; by which means we came within 350 years of the Arabian voyage published by Renaudot, and have but a small interval between the limit of ancient geography and that of the moderns.
From this author we first learn that the Persians having overcome the aversion of their ancestors to maritime enterprise, had established a flourishing and lucrative commerce with India. All its principal ports were visited by Persian merchants; and in most of the cities there were churches in which the service was performed by priests, ordained by a Persian archbishop.
We shall conclude our notice of Ceylon, as described by Cosmas, from the account of Sopatrus, with mentioning a few miscellaneous particulars, illustrative of the produce and commerce of the island. The sovereignty was held by two kings; one called the king of the Hyacinth, or the district above the Ghants, where the precious stones were found; the other possessed the maritime districts. In Ceylon, elephants are sold by their height; and he adds, that in India they are trained for war, whereas, in Africa, they are taken only for their ivory. Various particulars respecting the natural history of Ceylon and India, &c. are given, which are very accurate and complete: the cocoa-nut with its properties is described: the pepper plant, the buffalo, the camelopard, the musk animal, &c.: the rhinoceros, he says, he saw only at a distance; he procured some teeth of the hippopotamus, but never saw the animal itself. In the palace of the king of Abyssinia, the unicorn was represented in brass, but he never saw it. It is extraordinary that he makes no mention of cinnamon, as a production of Ceylon.
