Only a short period of life seemed allotted to the invalid ruler, and the service of the time-honoured god of the dead, to whom he had erected one of the most magnificent temples in the world at Alexandria, to which Egyptians and Hellenes repaired with equal devotion, opened hopes for the life after death which seemed to him worthy of examination.

For this reason also he desired to secure the favour of the Egyptian priesthood.

For this purpose, for the execution of his wise and beneficent arrangements, as well as for the gratification of his expensive tastes, large sums of money were required; therefore he devoted himself with especial zeal to enlarging the resources of his country, already so rich by nature.

In all these things he had found an admirable assistant in his sister Arsinoe.  As the daughter of the father and mother to whom he himself owed existence, he could claim for her unassailable legitimacy the same recognition from the priesthood, and the same submission from the people rendered to his own person, whom the religion of the country commanded them to revere as the representative of the sun god.

As marriages between brothers and sisters had been customary from ancient times, and were sanctioned by religion and myth, he had married the second Arsinoe, his sister, immediately after the banishment of the first Queen of this name.

After the union with her, he called himself Philadelphus—­brotherly love —­and honoured his sister and wife with the same name.

True, this led the sarcastic Alexandrians to utter many a biting, more or less witty jest, but he never had cause to regret his choice; in spite of her forty years, and more than one bloody deed which before her marriage to him she had committed as Queen of Thrace and as a widow, the second Arsinoe was always a pattern of regally aristocratic, dignified bearing and haughty womanly beauty.

Though the first Philadelphus could expect no descendants from her, he had provided for securing them through her, for he had induced her to adopt the first Arsinoe’s three children, who had been taken from their exiled mother.

Arsinoe was now accompanying her royal husband Philadelphus to the eastern frontier.  There the latter expected to name the city to be newly founded “Arsinoe” for her, and-to show his esteem for the priesthood—­to consecrate in person the new Temple of Tum in the city of Pithom, near Heroopolis.

Lastly, the monarch had been endeavouring to form new connections with the coast countries of eastern Africa, and open them to Egyptian commerce.

Admiral Eumedes, the oldest son of Philippus and Thyone, had succeeded in doing this most admirably, for the distinguished commander had not only founded on the Ethiopian shore of the Red Sea a city which he named for the King “Ptolemais,” but also won over the princes and tribes of that region to Egypt.

He was now returning from Ethiopia with a wealth of treasures.
