Nor was Romulus after this seen on earth.

The consternation being at length over, and fine clear weather succeeding so turbulent a day, when the Roman youth saw the royal seat empty, though they readily believed the fathers who had stood nearest him, that he was carried aloft by the storm, yet, struck with the dread as it were of orphanage, they preserved a sorrowful silence for a considerable time.
