The frog being caught is kept all night in an ark or chest; as it is written, ‘Thou didst not abhor the Virgin's Womb’, and this is an omen of good success. Dawn being come, thou shalt approach the chest with an offering of gold, and if available of frankincense and of myrrh. Thou shalt then release the frog from the chest with many acts of homage and place it in apparent liberty. He may, for example, be placed on a quilt of many colours, and covered with a net.
