1. Why did French artist, Frederic Sorrieu prepare a sries of printu prepare a scries of print based on democratic and socialistrepublics in 1848? |
|
Answer» Frederic Sorrieu, a French artist, brought out a series of four prints in 1848. These prints depicted his dream of a world made up of ‘democratic and social Republics’. The first of the four prints, depicts all the different people of Europe and America, irrespective of age, sex or class, marching and saluting to the statue of Liberty as they pass by it. The Statue of Liberty bears a torch symbolizing Enlightenment in one hand and the Charter of the Rights of Man in the other. While on the earth in the front of the statue lie the shattered remains of the symbols of absolutist institutions like crown, sceptre in the background the depictions of religious images and symbols guarantee divine approval. The word 'Fraternity' proclaiming Universal Brotherhood is written in the background. Sorrieu's Utopian vision had the peoples of the world grouped as distinct nations, identified through their flags and national costume. This represents the different people of the world grouped under their own nations with symbols of their nationalism like flag and national costume. |
