n--that it casts no shadow till it has been risen an
hour, and that the evening twilight lasts three hours after it has set; it
is obvious that the information of that age (of which we may justly suppose
the library of Alexandria was the great depository) did not extend beyond
Sabaea.

That Agatharcides had access to and made ample use of the journal of
Nearchus (of which we have given such a complete abstract), is evident from
various parts of his work; but it is also evident, by comparing his
description of those countries and their inhabitants, which had been
visited and described by Nearchus, that he had access to other sources of
intelligence, by means of which he added to the materials supplied by the
latter.

It will be recollected that Nearchus describes in a particular manner, the
Icthyophagi of Gadrosia: Agatharcides also describes Icthyophagi, though it
is not clear whether he means to confine his description to those of
Gadrosia, or to extend it to others on the coast of Arabia and Africa. The
mode practised by the Icthyophagi, according to him, is exactly that which
was practised by them in catching fish, according to Nearchus: he also
coincides with that author in various other particulars respecting the use
of the bones of whales, or other large fish, in the construction of their
houses; their ignorance and barbarism, their dress and mode of life. All
this he probably borrowed from Nearchus; but he adds one circumstance which
indubitably proves, that the knowledge of the eastern part of the world had
considerably advanced since the era of Alexander: he expressly states, that
beyond the straits that separate Arabia from the opposite coast, there are
an immense number of islands, scattered, very small, and scarcely raised
above the surface of the ocean. If we may advert to the situation assigned
to these islands, on the supposition that the straits which separate Arabia
from the opposite coast, mean the entrance to the Gulph of Persia, we shall
not be able to ascertain what these islands are; but if in addition to the
circumstances of their being scattered, very small, and very low, we add
what Agatharcides also notices, that the natives have no other means of
supporting life but by the turtles which are found near them in immense
numbers, and of a very large size, we shall be disposed, with Dr. Vincent,
to consider these as the Maldive Islands. It may be objected to this
supposition, that the Maldives are
