This noun designates the pre-dawn hour marked by roosters crowing, used to denote the third watch of the night. In Mark 13:35, Jesus lists the night watches including 'cock-crow,' situating it between midnight and dawn. Classical Greek used this compound for this specific time marker in the Roman watch system. The multilingual glosses (Spanish 'canto-de-gallo', French 'chant-du-coq', German 'Hahnenschrei') all reference the rooster's cry as a temporal indicator, crucial for understanding Jesus' predictions about Peter's denial.
