He studied in Paris and was influenced by the Italian Renaissance masters. Aman is known for his paintings of historic scenes, as well as for his landscape paintings of the Câmpulung-Muscel area, where he was born.

Among his most famous paintings are Michael the Brave's last night (Cea din urmă noapte a lui Mihai Viteazul), The Battle of Oltenița (Bătălia de la Oltenița), The Princedoms' Union (Unirea Principatelor) and Tudor Vladimirescu.
