SEA POPPY
The Sea Poppy or Horned Poppy (Glaucium) is named after Glaucus, a Bœotian fisherman, who, whilst pursuing his calling, observed that all the fishes which he laid on the grass received fresh vigour as they touched the ground, and immediately escaped from him by leaping back into the sea. He attributed the cause of it to some herb growing among the grass, and upon tasting the foliage of the Sea Poppy, he found himself suddenly moved with an intense desire to live in the sea. Upon this he leaped into the water, and was made a sea god by Oceanus and Tethys. This Glaucium or Sea Poppy was called in the middle ages Ficus infernalis: it was supposed to possess magical properties, and was prized by witches and sorcerers, who used it in their incantations. Ben Jonson, in the ‘Witches’ Song,’ says:—
Borlase tells us that, in the Scilly Isles, “this root (the Sea Poppy), so much valued for removing all pains in the breast, stomach, and intestines, is good also for disordered lungs, and is so much better here than in other places, that the apothecaries of Cornwall send hither for it; and some people plant them in their gardens in Cornwall, and will not part with them under sixpence a root. A very simple notion they have with regard to this root, which falls not much short of the Druids’ superstition in gathering and preparing their Selago and Samolus. This root, you must know, is accounted very good both as an emetic and cathartic. If, therefore, they design that it shall operate as the former, their constant opinion is that it should be scraped and sliced upwards—that is, beginning from the root, the knife is to ascend towards the leaf; but if it is intended to operate as a cathartic, they must scrape the root downwards.”
