When I was in Egypt before Christmas, I got bitten to pieces by mosquitos. On mentioning this, David Miller tells me that “canopy” is derived from the Greek word for mosquito-net.
The word is “k0n0peion”. The derivation is via late Lat. ‘canopeum’ — perhaps with a supposed connection to ‘Canopus’ .
k0n0ps (??”cone-face”??) = mosquito.
Imagine all those hard-bitten Greek mercenaries working for the late Pharaohs in the Nile Delta getting bitten, eh?
