The Sphynx: a hundred and twenty-five feet long, sixty feet high, and a hundred and two feet around the head, if I remember rightly--carved out of one solid block of stone harder than any iron. The block must have been as large as the Fifth Avenue Hotel before the usual waste (by the necessities of sculpture) of a fourth or a half of the original mass was begun. I only set down these figures and these remarks to suggest the prodigious labor the carving of it so elegantly, so symmetrically, so faultlessly, must have cost. This species of stone is so hard that figures cut in it remain sharp and unmarred after exposure to the weather for two or three thousand years. Now did it take a hundred years of patient toil to carve the Sphynx?
It seems probable.
