“The Only Deep Truth to Paint”
To paint can mean to apply cosmetics, to falsify.
Let her paint an inch thick
– Hamlet about his mother (5.1.184)
I have heard of your paintings too, well enough. God hath given you one face, and you make yourselves another ….. To a nunnery [brothel], go.
– Hamlet to Ophelia (3.1.142)
As C.T. Onions states, painting can be “specious, feigned, unreal.”*
And artistic painting can also be untrue.
