As Hester surveys the crowd she recalls her former english home. What four faces does she then remember?

Her father, her mother, herself, and Roger Chillingworth.

"She saw her father's face, with its bold brow, and reverend white beard, that flowed over the old-fashioned Elizabethan ruff; her mother's, too, with the look of heedful and anxious love which it always wore in her remembrance, and which, even since her death, had so often laid the impediment of a gentle remonstrance in her daughter's pathway. She saw her own face, glowing with girlish beauty, and illuminating all the interior of the dusky mirror in which she had been wont to gaze at it. There she beheld another countenance, of a man well stricken in years, a pale, thin, scholar-like visage, with eyes dim and bleared by the lamp-light that had served them to pore over many ponderous books. Yet those same bleared optics had a strange, penetrating power, when it was their owner's purpose to read the human soul."
