Renowned and prolific classical artists have a recognizable style to their paintings, but with so many artists to study, who can recognize them all? Redditor DontTacoBoutIt has some simple rules for that. For example, a painting with dappled light will be a Manet if the people look depressed, a Renoir if the people are happy, and if there are no people at all, it's Monet.
The Redditor’s explanations about how well-known artists can be recognized at a single glance are as informative as they are blunt and funny. For example, you can know almost for sure that a painting was done by Peter Paul Rubens if everyone’s naked and they all have very large derrières (‘butts’, the word means ‘butts’). And if everyone in a painting looks a bit like Russia’s leader Vladimir Putin, then you can bet your hat that it’s probably Jan van Eyck’s work.
See a roundup of these rules with examples that show how true they are at Bored Panda. The paintings above, obviously, are by Jan van Eyck.
