Did Vincent van Gogh die after cutting off his ear?

Yes, Vincent Van Gogh cut his left earlobe off December 24, 1888, because he had had an argument with one of his friends. The argument may have been whether Paul Gauguin was going to leave Arles, where they had been working together.

Nobody was with Vincent van Gogh when he cut off his ear. He used a razor (a very sharp kind of knife) to cut it off; he was in deep depression after his friend Paul Gauguin had been mad at him.

Van Gogh suffered from mental illness. He gave the blood-covered part of his ear to a prostitute he knew, not to his loved one, whom he didn't have. Later he shot himself and died in his room in Arles.
