Plutarch
Notes
Plutarch (c. 46–c. 120 AD), Greek biographer and Platonist philosopher, a priest at Delphi and a Roman citizen. His Parallel Lives paired Greek and Roman statesmen and was Shakespeare's source for the Roman plays. The Life of Theseus contains the first recorded statement of the Ship of Theseus puzzle, noting that the Athenians preserved the ship by replacing its planks and that philosophers disagreed about whether it remained the same ship.
