Nero, in fact, had a romantic charm about him, in spite of, or perhaps because of, the wild recklessness of his life; and he possessed the redeeming feature of artistic taste. Like Francis I. of France, or our own Charles II., he was irresistible with the ladies, and must have been the darling of all the housemaids of Rome. People long refused to believe in his death, and for many years it was confidently affirmed that he would appear again. His ghost was long believed to walk in Rome, and the church of Santa Maria del Popolo is said to have been built as late as 1099 by Pope Paschalis II. on the site of the tombs of the Domitii, where Nero was buried, near the modern Porta del Popolo, where the Via Flaminia entered the city, in order to lay his restless shade. Caligula also appeared shortly after his death, and frequently disturbed the keepers of the Lamian Gardens, for his body had been hastily buried there without due ceremony. Not till his sisters, who really loved him, in spite of his many faults, had returned from exile were the funeral rites properly performed, after which his ghost gave no more trouble.[83] On the night of the day of Galba's murder, the Emperor Otho was heard groaning in his room by his attendants. They rushed in, and found him lying in front of his bed, endeavouring to propitiate Galba's ghost, by whom he declared that he saw himself being driven out and expelled.[84] Otho was a strange mixture of superstition and scepticism, for when he started on his last fatal expedition he treated the unfavourable omens with contempt. By this time, however, he may have become desperate. Moreover, irreligious people are notoriously superstitious, and at this period it would be very difficult to say just where religion ended and superstition began.
