prosopography \pros-uh-POG-ruh-fee\, noun:
1. A description of a person’s appearance, career, personality, etc.
2. A study of a collection of persons or characters, esp. their appearances, careers, personalities, etc., within a historical, literary, or social context.
Prosopography ultimately originates in the combination of the Greek roots prosopon, “face, or person,” and graphia, “writing of.”
If I ever had 10 years to spare, I would gladly spend them on a prosopography of Fyodor Dostoyevsky.
