Edwyn Bevan 
History of Egypt under the Ptolemaic Dynasty (Routledge Revivals) [PDF ebook] 

First published in 1927, this title presents a well-regarded study of this intriguing and often over-looked period of Egyptian history, both for the general reader and the student of Hellenism.Edwyn Bevan describes his work as ‘an attempt to tell afresh the story of a great adventure, Greek rule in the land of the Pharaohs…which ends with the astounding episode of Cleopatra’. The result is a remarkable synthesis of historical scholarship, prose style and breadth of vision, which will still prove to be of value to Egypt enthusiasts and students of Egyptology.
