So saying, he set off round all the woods and clearings, and organized a herd of stags into a single line; so, too, with does and with she-goats. He seated himself on a stag, and at the coming of the day he set off, driving his lines before him. So he came with speed to the place of Guendoloena's wedding. Arriving there, he made the stags stand quietly outside the gates, then shouted, "Guendoloena, Guendoloena, come out! What presents are looking for you!" Guendoloena came quickly, all smiles, and was astonished to see a man riding a stag and it obeying him, astonished that so many animals of the wild could be brought together and that he alone was driving them before him like a shepherd accustomed to taking his sheep to pasture.
