I did not indeed select for my hero the recluse, nor for my heroines the twins who are spoken of in the petitions, but others who might have lived at a somewhat earlier date under similar conditions; for it is proved by the papyrus that it was not once only and by accident that twins were engaged in serving in the temple of Serapis, but that, on the contrary, pair after pair of sisters succeeded each other in the office of pouring out libations. I have not invested Klea and Irene with this function, but have simply placed them as wards of the Serapeum and growing up within its precincts. I selected this alternative partly because the existing sources of knowledge give us very insufficient information as to the duties that might have been required of the twins, partly for other reasons arising out of the plan of my narrative. Klea and Irene are purely imaginary personages, but on the other hand I have endeavored, by working from tolerably ample sources, to give a faithful picture of the historical physiognomy of the period in which they live and move, and portraits of the two hostile brothers Ptolemy Philometor and Euergetes II., the latter of whom bore the nickname of Physkon: the Stout. The Eunuch Eulaeus and the Roman Publius Cornelius Scipio Nasica, are also historical personages. I chose the latter from among the many young patricians living at the time, partly on account of the strong aristocratic feeling which he displayed, particularly in his later life, and partly because his nickname of Serapion struck me. This name I account for in my own way, although I am aware that he owed it to his resemblance to a person of inferior rank. For the further enlightenment of the reader who is not familiar with this period of Egyptian history I may suggest that Cleopatra, the wife of Ptolemy Philometor--whom I propose to introduce to the reader--must not be confounded with her famous namesake, the beloved of Julius Caesar and Mark Antony. The name Cleopatra was a very favorite one among the Lagides, and of the queens who bore it she who has become famous through Shakespeare (and more lately through Makart) was the seventh, the sister and wife of Ptolemy XIV. Her tragical death from the bite of a viper or asp did not occur until 134 years later than the date of my narrative, which I have placed 164 years B.C. At that time Egypt had already been for 169 years subject to the rule of a Greek (Macedonian) dynasty, which owed its name as that of the Ptolemies or Lagides to its founder Ptolemy Soter, the son of Lagus. This energetic man, a general under Alexander the Great, when his sovereign--333 B.C.--had conquered the whole Nile Valley, was appointed governor of the new Satrapy; after Alexander's death in 323 B.C., Ptolemy mounted the throne of the Pharaohs, and he and his descendants ruled over Egypt until after the death of the last and most famous of the Cleopatras, when it was annexed as a province to the Roman Empire.
