In Brazil I like Carlos Drummond de Andrade, a poet, and Graciliano Ramos. I like painters such as Portinari, Tarcila do Amaral and Volpi.
Painters - Kossak, Gierymski, Matejko, Witkiewicz (also a writer)
Writers - Sienkiewicz, Żeromski, Mickiewicz, Słowacki, Krasiński, Norwid, Wyspiański (also a painter), Reymont.
There's a lot of them, most were living under the Partitions of Poland (between 1795 and 1918).
There are some, more modern writers, but I don' like them.
In Brazil, Machado de Assis and Guimarâes Rosa are some of the most important writers. The most famous contemporary painters are Vik Muniz, Cildo Meireles and Sandra Cinto. I like them a lot.
