Etymology

Origin of sub rosa

First recorded in 1650–60; from Latin sub rosā literally, “under the rose,” from the ancient use of the rose at meetings as a symbol of the sworn confidence of the participants, based on the Greek myth that Aphrodite gave a rose to her son Eros, who then gave the rose to Harpocrates, the god of silence and secrets, to ensure that Aphrodite’s dalliances remained hidden
