Early in 1897 a landslip on the tall cliffs of Halzaphron--which face upon Mount's Bay, Cornwall, and the Gulf Stream of the Atlantic--brought to light a curiosity. The slip occurred during the night of January 7th to 8th, breaking through the roof of a cavern at the base of the cliff and carrying many hundreds of tons of rock and earth down into deep water. For some weeks what remained of the cavern was obliterated, and in the rough weather then prevailing no one took the trouble to examine it; since it can only be approached by sea. The tides, however, set to work to sift and clear the detritus, and on Whit-Monday a party of pleasure-seekers from Penzance brought their boat to shore, landed, and discovered a stairway of worked stone leading up from the back of the cavern through solid rock. The steps wound spirally upward, and were cut with great accuracy; but the drippings from the low roof of the stairway had worn every tread into a basin and filled it with water. Green slippery weeds coated the lowest stairs; those immediately above were stained purple and crimson by the growth of some minute fungus; but where darkness began, these colors passed through rose-pink into a delicate ivory-white--a hard crust of lime, crenelated like coral by the ceaseless trickle of water which deposited it. At first the explorers supposed themselves on the track of a lost holy well. They had no candles, but by economising their stock of matches they followed up the mysterious and beautiful staircase until it came to a sudden end, blocked by the fallen mass of cliff. Still in ignorance whither it led or what purpose it had served, they turned back and descended to the sunshine again; when one of the party, scanning the cliff's face, observed a fragment--three steps only--jutting out like a cornice some sixty or seventy feet overhead. This seemed to dispose of the holy well theory, and suggested that the stairway had reached to the summit, where perhaps an entrance might be found. The party returned to Penzance, and their report at once engaged the attention of the local Antiquarian Society; a small subscription list was opened, permission obtained from the owner of the property, and within a week a gang of labourers began to excavate on the cliff-top directly above the jutting cornice. The ground here showed a slight depression, and the soil proved unexpectedly deep and easy to work. On the second day, at a depth of seven feet, one of the men announced that he had come upon rock. But having spaded away the loose earth, they discovered that his pick had struck upon the edge of an extremely fine tessellated pavement, the remains apparently of a Roman villa.
