In a one-page-essay, explain why do you think Michelangelo chose to sculpt his Moses (2.4.8) from marbles, and Marcel Duchamp decided to appropriate a urinal (3.10.1) in order to declare it a work of art? 

Look at the materials used by the artists and the unique qualities-the durability of stone, the shininess of the ceramic glaze-try to see what associations the artist may have in mind when they chose the material or process. 

What is your personal opinion about the artists’ works and messages. 

2.4.8 Michelangelo. Tomb of Julius II, Detail of Moses, 1513-16. Marble

3.10.1 Marcel Duchamp, Fountain, 1950 (replica of original from 1917). Porcelain urinal
