I. In writing the Lives of Alexander the Great and of Cæsar the conqueror of Pompeius, which are contained in this book, I have before me such an abundance of materials, that I shall make no other preface than to beg the reader, if he finds any of their famous exploits recorded imperfectly, and with large excisions, not to regard this as a fault. I am writing biography, not history; and often a man's most brilliant actions prove nothing as to his true character, while some trifling incident, some casual remark or jest, will throw more light upon what manner of man he was than the bloodiest battle, the greatest array of armies, or the most important siege. Therefore, just as portrait painters pay most attention to those peculiarities of the face and eyes, in which the likeness consists, and care but little for the rest of the figure, so it is my duty to dwell especially upon those actions which reveal the workings of my heroes' minds, and from these to construct the portraits of their respective lives, leaving their battles and their great deeds to be recorded by others. II. All are agreed that Alexander was descended on his father's side from Herakles through Karanus, and on his mother's from Æakus through Neoptolemus. We are told that Philip and Olympias first met during their initiation into the sacred mysteries at Samothrace, and that he, while yet a boy, fell in love with the orphan girl, and persuaded her brother Arymbas to consent to their marriage. The bride, before she consorted with her husband, dreamed that she had been struck by a thunderbolt, from which a sheet of flame sprang out in every direction, and then suddenly died away. Philip himself some time after his marriage dreamed that he set a seal upon his wife's body, on which was engraved the figure of a lion. When he consulted the soothsayers as to what this meant, most of them declared the meaning to be, that his wife required more careful watching; but Aristander of Telmessus declared that she must be pregnant, because men do not seal up what is empty, and that she would bear a son of a spirited and lion-like disposition. Once Philip found his wife asleep, with a large tame snake stretched beside her; and this, it is said, quite put an end to his passion for her, and made him avoid her society, either because he feared the magic arts of his wife, or else from a religious scruple, because his place was more worthily filled. Another version of this story is that the women of Macedonia have been from very ancient times subject to the Orphic and Bacchic frenzy (whence they were called Clodones and Mimallones), and perform the same rites as do the Edonians and the Thracian women about Mount Haemus, from which the word "threskeuein" has come to mean "to be over-superstitious." Olympias, it is said, celebrated these rites with exceeding fervour, and in imitation of the Orientals, and to introduce into the festal procession large tame serpents,[394] which
