I think this is probably the incident in 1485 of the finding of the intact body of a girl in a Roman sarcophagus - she was popularily identified as Cicero's daughter Tulliola and people flocked to see her until Pope Innocent VIII had her removed. You'll find a brief account and some further bibliography in R. Weiss, The Renaissance Discovery of Classical Antiquity (Oxford, 1969) (2nd ed. 1988 p.102).
