Hinc illae lacrimae
Hinc illae lacrimae (Latin for "hence those/these tears") is a line from the comedy Andria (166 BC), by the Roman poet Terence. Since the time of the Roman Republic, the phrase has been appropriated as a popular saying or quotation, to be employed when a previously-obscured reason or explanation—for some action(s) or behavior—is recognized; and, especially, when a baser motivation is thereby identified, contra an (initially-assumed) nobler one.
