"Semeadores" by Diego Rivera

SOAPSTone the painting.
Subject: Something about workers and agriculture/planters.
Occasion: Early 20th century roundabouts
Audience: Anyone who does not have to work on a regular basis.
Purpose: To show workers hard at work, make them think that these people have to work hard for something.
Speaker: Diego Rivera is a Mexican painter known for his championing of the working class and for his interest in history and his political messages.
Tone: He looks to me to be showing workers in a good light, because of all the rather bright colors, though the dark sky does add some foreboding.

I think it was trying to show how hard workers have to work, and to cast working for your earnings in a food light. The lighting itself is very bright, and all the curves make them look more nice looking and harmonious. It casts them in a very simple light, as if their lives are all very simple and down to earth, as you can tell by how the lines of the workers blend in with the lines of the ground behind them.
