And he made by magic twelve stallions and twelve greyhounds, each of them black but white breasted, and twelve collars and leashes upon them; and twelve saddles on the horses, and any one that saw them would not know but that the workmanship was all of gold.
With the horses and the dogs he came to Pryderi. ÔLord,Õ he said, Ôhere is an exchange for thee for the swine.Õ ÔWhy,Õ said he, Ôwe will take counsel.Õ They found in their counsel to give Gwydion the swine, and take from him in return the horses and the dogs.
And then they took leave and started off with the swine. ÔMy brave lads,Õ said Gwydion, Ôwe must needs shift in haste. The spell will last but one day till the morrow.Õ
