Marcus Licinius Crassus Agelastus
M. Crassus (Agelastus)
also: M. Crasso, M. Crassus, Agelastos Crassus, the man who laughed but once
A Roman of the early first century BC, grandfather of the triumvir Crassus, proverbially said by Lucilius to have laughed only once in his life, earning the nickname 'agelastos' (never-laughing). Cicero cites him in De Finibus 5.92 to argue that one lapse from cheerfulness does not destroy a cheerful life.
