While the Italians can be considered the archetypical Baroque painters (in that they are what most people think of when the subject comes up), two other regions gave us some fine examples of the style. Very similar in philosophy and results, the artists of Spain and of Flanders (whom I must separate from those of the Dutch school, since the styles are really different) stand as the second line of Baroque painting. Some people might say first, and they have an argument, but I just like the Italians better, so there.
Bartolomeo Murillo, who painted street urchins very well.
Jusepe Ribera, Apollo Flaying the Satyr Marsyas
Diego Rodriguez Velasquez, considered an all-time Art Star for this painting
although I prefer this one
Francisco de Zurbaran
My favorite Spanish painter, St Agatha and her ta-tas
Jacob Jordaens with my second favorite picture of all time
Anton Van Dyck, who's statue almost beheaded me, but I won't hold it agin him
Cupid and Psyche
Peter Paul Rubens, whom I dislike and who's name I don't pronounce correctly (but whom many people consider the ne plus ultra of the Baroque)
Descent from the Cross
