Born to a wealthy family, he went to Trieste, Italy, in 1856 where he began painting. He studied in the Munich Academy of Fine Arts. He is one of the foremost representatives of the Munich School, a Greek artistic style of the 19th century. Michalis Oikonomou, another Greek painter, was one of his pupils.
