A plate and two marine creatures

Another day spent stripping wall paper. I used to think that if I were to end up in Hell then I would spend eternity changing duvet covers in an infinitely long corridor of hotel bedrooms. Now I know that I was being far too optimistic, I see now that I shall be  be eternally stripping the wallpaper from the rooms!
To cheer myself up here is another Lotte Glob ceramic, this time a plate. It always reminds me of a rock pool and so I have added a couple of marine creatures. In recognition of Lotte Glob being the daughter of Peter Vilhelm Glob the famous archaeologist I have chosen two very old creatures, each of some archaeological interest. One is marine snail called Murex brandaris, the other a crushing tooth from a skate, or a ray. I picked them up in Tunisia from the spoil heaps created during the excavation of the Roman town of Colonia Julia Neapolis in Tunisia.
The snail was one of the species used by the ancients to produce the purple fabric dye known as Tyrian purple, or royal purple, or imperial purple. 
The skate tooth was from a Roman garum works. Garum was a fish sauce, presumably similar to modern Thai fish sauce, greatly appreciated in Roman times as a seasoning. It was made by fermenting masses of rotting fish in the heat of the sun, for weeks on end, in vast sunken vats.
