All of Michelangelo will endure. He is an outlier of outliers and the greatest visual artist of all-time, bar none. David may not even be his best sculpture carved and chiseled from a single block of marble (although I do think so) given that Pieta exists, but either way, they're #1 and #2. He also painted the most ambitious and iconic fresco in the history of Western art on the ceiling of the Sistine Chapel alongside another monumental one on its altar wall. He was a principal architect of the largest church in the world, fully responsible for its dome and drum.
It's been subpar for a minute.
