Edwyn Robert Bevan, The House of Ptolemy — Chapter II: Ptolemy I… (1927)
“ Through the forty years of struggle which followed between the great Macedonian chiefs — the men who had learnt war under Alexander — Ptolemy, the son of Lagus, remained in his African province, safe as a tortoise in his shell, while armies marched to and fro across Asia and rival fleets battled in the Aegean. To some extent, indeed, he stretched forth out of his shell to mingle in the mellay, for the power ruling Egypt was now one of Hellenistic character, having various connexions, political, economic, cultural, with the other states of the Greek world. ”
