Snakes in a love tangle - inside the church

Intertwined snakes on a miserichord seat in St David's cathedral Pembrokeshire, Wales. These snakes have nodules along the spine, just as medieval dragons do. They may have been inspired what the medieval monk Bartholomaeus Anglicus writes about the love that adders have for their mates. "This slaying adder and venomous hath wit to love and affection, and loveth his mate as it were by love of wedlock, and liveth not well without company. Therefore if the one is slain, the other pursueth him that slew that other with so busy wreak and vengeance, that passeth weening. And knoweth the slayer, and reseth on him, be he in never so great company of men and of people, and busieth to slay him, and passeth all difficulties and spaces of ways, and with wreak of the said death of his mate. And is not let, ne put off, but it be by swift flight, or by waters or rivers."
