I stumbled across this Sphinx in the sand at Newgale in Pembrokeshire some days ago. There was also a rather fine pyramid. Both works of art were about to fall victim to the sea as it raced up the beach.
I couldn't help thinking of Ozymandias ...
I was also curious to discover how many poems I could call to mind concerning both the sphinx of Egypt and the sphinx of Oedipus and Theban mythology.
Oscar Wilde, Ralph Waldo Emerson and Sophocles come immediately to mind.
