Perhaps it was the candle that brought to mind Uncle Lamb and the day he’d told me about vestal virgins, showing me a blue chalcedony carving from the temple of Vesta. “Should a virgin betray her vows,” he’d said, waggling his eyebrows at me, “she’d be whipped, then sealed up alive in a small underground tomb, equipped with a table and chair, some water, and a single candle. And there she would die, when the air ran out.”
