“While painting Italia und Germania, Overbeck wrote to his friend Friedrich Ludwig Zacharias Werner (a German poet, dramatist and preacher):

Italia and Germania are both somewhat elements, that on one hand, confront each other with a foreign presence,but however my mission is now to melt them into one. It is on one hand a tribute to the homeland and on the other, a charm of everything beautiful and lordly, for which I am thankful to enjoy presently”
