Above is a piece by michelangelo, called the holy family. explain the term modeling in art and why michelangelo was considered a master of modeling

Modeling was quite similar to the models of today; the only difference being that the models were not photographed. Michelangelo spent a lot of time studying his muses and models, so he could get every single detail correct. That is why his statues and paintings are so realistic, he put an absurd amount of effort into his work, and it definitely paid off.

The term collage was coined by both  georges braque  and  pablo picasso  in the beginning of the 20th century when collage became a distinctive part of modern art.hope this sorry if there wasn't more of an explanation!
