this may be too late... but here it is anyways. cezanne was a great impressionist painter who used painted still lives, portraits, and landscapes in a different way. he did many still lives. like how van gogh sure liked sunflowers, cezanne liked apples. he saw them not as apples, but as a form of shapes and colors. apples are popular artist still life models. if you actually try to paint an apple, and not dissect it into shapes, forms, and color, you'll end up with a kind of bad representation of an apple. impressionists, and post-impressionists were in competition with photographers at the time. photographers basically stole the thunder of the painters. so they came up with a new way to look at things. something photography couldnt do. thats basically what cezanne's intentions for the apple still lives.
picasso abstracted his still live. its like a hierarchy in imagery. realim, impressionism, abstract. theres other styles in and arund that, but whatever. abstract is more of an imagination rather than truth. if you look long and hard, you'll see bits and pieces of a bottle. but picasso doesnt want things to be that simple. he also incorporated ofther things in the painting thats not rum bottle. like, theres refference to msheet music, spanish wine bottles, letters (which may be from the bullfighting magazine "el torero" or it could just be him being a dork, and putting "LETR" in there because it his 1st time using letters in his painting, and he just wanted to incorporate it as a joke for being "letra" spanish for word, or "lettre" french for word.
