Atticus's maternal uncle, a wealthy and notoriously difficult moneylender whose estate Atticus eventually inherited (taking the name Q. Caecilius Pomponianus Atticus). At Att 1.1.3-4 he is defrauded by P. Varius and asks Cicero to appear against A. Caninius Satyrus, which Cicero declines, straining their relations.
