The hosts were to march after the festival of the New Year, which Cambyses celebrated this time with immense expense and profusion.  The ceremony over, he betook himself to the army.  Bartja was there.  He came up to his brother, beaming with joy, kissed the hem of his robe, and told him in a tone of triumph that he hoped to become a father.  The king trembled as he heard the words, vouchsafed his brother no answer, drank himself into unconsciousness that evening, and the next morning called the soothsayers, Magi and Chaldaeans together, in order to submit a question to them.  “Shall I be committing a sin against the gods, if I take my sister to wife and thus verify the promise of the dream, which ye formerly interpreted to mean that Atossa should bear a future king to this realm?”

The Magi consulted a short time together.  Then Oropastes cast himself at the king’s feet and said, “We do not believe, O King, that this marriage would be a sin against the gods; inasmuch as, first:  it is a custom among the Persians to marry with their own kin; and secondly, though it be not written in the law that the pure man may marry his sister, it is written that the king may do what seemeth good in his own eyes.  That which pleaseth thee is therefore always lawful.”

Cambyses sent the Magi away with rich gifts, gave Oropastes full powers as regent of the kingdom in his absence, and soon after told his horrified mother that, as soon as the conquest of Egypt and the punishment of the son of Amasis should have been achieved, he intended to marry his sister Atossa.

At length the immense host, numbering more than 800,000 fighting men, departed in separate divisions, and reached the Syrian desert in two months.  Here they were met by the Arabian tribes whom Phanes had propitiated—­the Amalekites and Geshurites—­bringing camels and horses laden with water for the host.

At Accho, in the land of the Canaanites, the fleets of the Syrians, Phoenicians and Ionians belonging to Persia, and the auxiliary ships from Cyprus and Samos, won by the efforts of Phanes, were assembled.  The case of the Samian fleet was a remarkable one.  Polykrates saw in Cambyses’ proposal a favorable opportunity of getting rid of all the citizens who were discontented with his government, manned forty triremes with eight thousand malcontent Samians, and sent them to the Persians with the request that not one might be allowed to return home.—­[Herod.  III. 44.]

As soon as Phanes heard this he warned the doomed men, who at once, instead of sailing to join the Persian forces, returned to Samos and attempted to overthrow Polykrates.  They were defeated, however, on land, and escaped to Sparta to ask help against the tyrant.

A full month before the time of the inundation, the Persian and Egyptian armies were standing face to face near Pelusium on the north-east coast of the Delta.

Phanes’ arrangements had proved excellent.  The Arabian tribes had kept faith so well that the journey through the desert, which would usually have cost thousands of lives, had been attended with very little loss, and the time of year had been so well chosen that the Persian troops reached Egypt by dry roads and without inconvenience.
