A few items I've learned recently.
- Cupid gave Harpocrates, the Greek god of Silence, a rose to insure Cupid's mother Aphrodite's many indiscretions would be kept quiet. This is the origin of our word "sub rosa" meaning to keep secret or quiet. Roses were carved into banquet hall roofs to signify that the wild things that happened would be "sub rosa". A medieval form of "What happens in Vegas, stays in Vegas." (It is just a coincidence that Harpo Marx never spoke - although Gracho claimed Harpo was named after Harpocrates, Harpo was named for playing the harp.)
- People born blind do not suffer from schizophrenia, but losing sight later in life increases the chance of schizophrenia.
- A portmanteau is a merging of two words to create another, like combining fan and magazine to yield fanzine.
