The 19th c painter CD Rosenthal has been an important figure of the 1848 Revolution in Wallachia, which has put the basis of the modern national identity of what a few decades later will become Romania. He was a Hungarian Jew, which made his contribution even more momentous in the pivotal moments that are at the origins of this modern nation state in southeast Europe. This video is a review of the commemorative exhibition of his works taking place this season at the National Museum of Art in Bucharest (MNAR). He was a recorder of those events and protagonists, in an era before the mass media, painting his friends, the revolutionaries, who were young local aristocrats, and other people who, like him of cosmopolitan background, came to identify themselves with the political movement that aimed to set up this new national state. One such personality was the Scottish woman, Mary Grant, the model for his most famous painting, ‘Revolutionary Romania’. The exhibition is an excellent breviary of a pivotal moment in the history of this country, which conditioned its cultural and political evolution ever after, including the outlook and directions of its architecture.
