Why does Botero paint fat people?
Maybe he likes fat people for some reason? Or he just enjoys painting them...
Originally Fernando Botero didn't set himself to paint a young Mona Lisa. He had painted a Colombian girl (aged 12). While he was living in New York City in the early sixties, the woman that cleaned Botero's apartment saw the painting and told him that it resembled the Mona Lisa. Botero picked-up on that comment, modified the painting and renamed it, Mona Lisa,age 12
"Fat" oil paint is oil paint right out of the tube. Mixing it with an oil makes it even "fatter" and increases the length of time it takes to dry. Mixing it with turpentine makes it "lean" and it will dry faster. A thicker, slower drying paint should be used after a thinner, faster drying paint to avoid cracking. In other words, "fat" over "lean".
