Herodotus was born at Halicarnassus, a town in Asia Minor, in the year B.C. 484. His family were rich, and having large commercial transactions they were able to encourage the taste for explorations which he showed. At this time there were many different opinions as to the shape of the earth: the Pythagorean school having even then begun to teach that it must be round, but Herodotus took no part in this discussion, which was of the deepest interest to learned men of that time, and, still young, he left home with a view of exploring with great care all the then known world, and especially those parts of it of which there were but few and uncertain data. He left Halicarnassus in 464, being then twenty years of age, and probably directed his steps first to Egypt, visiting Memphis, Heliopolis, and Thebes. He seems to have specially turned his attention to the overflow of the banks of the Nile, and he gives an account of the different opinions held as to the source of this river, which the Egyptians worshipped as one of their deities. "When the Nile overflows its banks," he says, "you can see nothing but the towns rising out of the water, and they appear like the islands in the AEgean Sea." He tells of the religious ceremonies among the Egyptians, their sacrifices, their ardour in celebrating the feasts in honour of their goddess Isis, which took place principally at Busiris (whose ruins may still be seen near Bushir), and of the veneration paid to both wild and tame animals, which were looked upon almost as sacred, and to whom they even rendered funeral honours at their death. He depicts in the most faithful colours, the Nile crocodile, its form, habits, and the way in which it is caught, and the hippopotamus, the momot, the phoenix, the ibis, and the serpents that were consecrated to the god Jupiter. Nothing can be more life-like than his accounts of Egyptian customs, and the notices of their habits, their games, and their way of embalming the dead, in which the chemists of that period seem to have excelled. Then we have the history of the country from Menes, its first king, downwards to Herodotus' time, and he describes the building of the Pyramids under Cheops, the Labyrinth that was built a little above the Lake Moeris (of which the remains were discovered in A.D. 1799), Lake Moeris itself, whose origin he ascribes to the hand of man, and the two Pyramids which are situated a little above the lake. He seems to have admired many of the Egyptian temples, and especially that of Minerva at Sais, and of Vulcan and Isis at Memphis, and the colossal monolith that was three years in course of transportation from Elephantina to Sais, though 2000 men were employed on the gigantic work.
