PILATE(S). Pontius Pilate, fl. first century A.D., was the prefect of Judaea from A.D. 26-36 who condemned Jesus to death. In medieval drama, he appears in plays of the Trial, Flagellation, and Passion of Christ.
The drunken Miller cries out "in Pilate's voice" that he can tell a tale equally as good as the Knight's, MillT 3124. "Pilates voys" was a high voice, something like a counter-tenor falsetto, which medieval actors used for the role in the cycle drama.
Pilates, the ME genitive case, appears medially.
