The King Must Die

The King Must Die is a 1958 bildungsroman and historical novel by Mary Renault that traces the early life and adventures of Theseus, a hero in Greek mythology. Naturally, it is set in Ancient Greece: Troizen, Corinth, Eleusis, Athens, Knossos in Crete, and Naxos. Rather than retelling the myth, Renault constructs an archaeologically and anthropologically plausible story that might have developed into the myth. She captures the essentials while removing the more fantastical elements, such as monsters and the appearances of gods. The King Must Die was lauded by critics, with New York Times reviewer Orville Prescott calling it "one of the truly fine historical novels of modern times." Renault wrote a sequel, The Bull from the Sea, in 1962.

On her portrayal of Theseus in her books, in her "Author's Note", p. 333
The King Must Die (1958)
Context: Men who hover over their opponents have no cause to evolve a science of wrestling; and Theseus is conventionally shown in combat with hulking of monstrous enemies, living by his wits. The tradition that he emulated the feats of Herakles may well embalm some ancient sneer at the over-compensation of a small assertive man. Napoleon comes to mind.
If one examines the legend in this light, a well-defined personality emerges. It is that of a light-weight; brave and aggressive, physically tough and quick; highly sexed and rather promiscuous; touchily proud, but with a feeling for the underdog; resembling Alexander in his precocious competence, gift of leadership, and romantic sense of destiny.
