Of these opinions the third, which is also given by Festus, seems to come nearest the truth. "Caesar" and "caesaries" are both probably connected with the Sanskrit "kêsa", "hair", and it is quite in accordance with the Roman custom for a surname to be given to an individual from some peculiarity in his personal appearance. The second opinion, which seems to have been the most popular one with the ancient writers, arose without doubt from a false etymology. With respect to the first, which was the one adopted, says Spartianus, by the most learned men, it is impossible to disprove it absolutely, as we know next to nothing of the ancient Moorish language; but it has no inherent probability in it; and the statement of Servius is undoubtedly false, that the grandfather of the dictator obtained the surname on account of killing an elephant with his own hand in Africa, as there were several of the Julii with this name before his time.
