The rose can also emblematically represent secrecy, and we see the phrase "sub rosa" which is Latin for "under the rose" used to denote secrecy or confidentiality. When assembled, if it was to be understood that anything said in the meeting was to never be repeated elsewhere, the Romans would hang roses from, or paint them on, the ceiling above the table - "sub rosa". The use of the rose as a symbol for secrecy goes back to ancient Greek and Egyptian mythology, where the rose was also a symbol for the god Horus (son of Isis). Although Horus was the sky god, represented by a man with a falcon for a head, he was sometimes represented as a child. In Egyptian artwork, the child was often represented by a naked child with his finger on his mouth as if sucking on it, to denote youth, but the Greeks misunderstood this gesture to mean "secrecy". The Greek's translated the name of Horus to which they now have the Harpocrates, the god of silence. It was adapted in Greek lore that Aphrodite gave her son, Eros (or Cupid), a rose. He in turn gave this rose to Harpocrates, god of silence, as a bribe to make sure that the indiscretions of the gods and goddesses were kept "under wraps", concealed. Harpocrates was often represented as a chubby infant with a finger to his mouth.
For the Secret Master, the candidate places two fingers to his lip and is told that his obligation "enjoins secrecy."
