As well as various characteristic rope patterns, it carries a strange picture of a man (Adam?), his son crushing the serpent’s head, and representations of the Holy Trinity with fish & dragons.
It came from Hampstead Norreys in Berkshire, and has only been in Stone since 1845. E. F. M. Watson described the design thus in 1906:
The Monster on the Left is the Evil One with open mouth and unknotted tail, free to destroy and hinder the free course of the Fish, that is the Christian Faith. On the right is the same Evil power, but a Hand is in its mouth and the tail is knotted; it is being subdued by the might of the Three Persons in the Holy Trinity, though it still holds in its claws a human head, whose expression is one of hopelessness and terror.The Church guide is a bit more down to earth:
The font which is Norman is richly carved all around the bowl, with scenes thought to depict the conflict between Satan and the Trinity. A dragon representing Satan is baring his teeth and waving his tail. We then see him muzzled by the arm of the Father, pecked by the Spirit in the form of a Dove, and having had his tail knotted by the Son.Reeling from this encounter with things fantastic, among other fine flower arrangements, I noticed a windowsill display containing Pitcher Plants — hardly your standard bunch of daffs, but they looked rather triffid-like and unusual. I imagine they also keep the flies down in the summer.
