Rupert Brooke wrote to a friend in 1914, and used the word
polypist. He wrote, "...so polypist and yet benevolent...". He added what to me was an amazing and
amusing note: "=of many faiths, not bespattered by a parrot, O Greekless!"

Did he make this word up, or perhaps mis-spell a real word?
I can't find it, nor come up with anything close to it.
