We were intending to continue our voyage, when we were discovered and detained by the Horse-vultures, as they are called. These are men mounted on huge vultures, which they ride like horses; the great birds have ordinarily three heads. It will give you some idea of their size if I state that each of their quill-feathers is longer and thicker than the mast of a large merchantman. This corps is charged with the duty of patrolling the land, and bringing any strangers it may find to the king; this was what was now done with us. The king surveyed us, and, forming his conclusions from our dress, 'Strangers,' said he, 'you are Greeks, are you not?' we assented. 'And how did you traverse this vast space of air?' In answer we gave a full account of ourselves, to which he at once replied with his own history. It seemed he too was a mortal, named Endymion, who had been conveyed up from our Earth in his sleep, and after his arrival had become king of the country; this was, he told us, what we knew on our Earth as the moon. He bade us be of good cheer and entertain no apprehensions; all our needs should be supplied. 'And if I am victorious,' he added, 'in the campaign which I am now commencing against the inhabitants of the Sun, I promise you an extremely pleasant life at my court.' We asked about the enemy, and the quarrel. 'Phaethon,' he replied, 'king of the Sun (which is inhabited, like the Moon), has long been at war with us. The occasion was this: I wished at one time to collect the poorest of my subjects and send them as a colony to Lucifer, which is uninhabited. Phaethon took umbrage at this, met the emigrants half way with a troop of Horse-ants, and forbade them to proceed. On that occasion, being in inferior force, we were worsted and had to retreat; but I now intend to take the offensive and send my colony. I shall be glad if you will participate; I will provide your equipment and mount you on vultures from the royal coops; the expedition starts to-morrow.' I expressed our readiness to do his pleasure.
