I bought nothing at the flea market today but stopped to admire a human skull from the sixth century. It’s on a stand, the head of a child, crazed with tiny lines, and exquisite. The woman selling it gave me the price, which amounted to $6,000. It seemed extravagant, but then, how do you value a skull? The way it is, I could buy either a decent used car or some kid’s head. It’s twice the cost of Hugh’s computer and half the price of a hysterectomy.
