Phantasmagorical Medieval Critters

[poliphilo]

The one at the top is a lion with the head of a snake (isn't here something of that kind in the Book of Revelation?) and the one at the bottom appears to have the body of a goose, the feet of a deer, a snaky neck and a human face enclosed in some sort of a hood. They appear on the font of St Mary's, Upavon, Wiltshire.
