Milan 1880 is an infamous historical mark of "slashing" sign language which led to the Dark Age of Deaf Education. At this biased, pre-planned conference, International Congress on Education of the Deaf in Milan, oralist proponents voted to ban sign language.
The work of art Milan, Italy 1880 by Mary J. Thornley is a visual metonym of the famous work The Executions of the Third of May 1808 (painted in 1814-1815) or the shorter title Third of May, 1808 by Francisco Goya (1746-1828), one of the great Spanish masters.
The Third of May by Goya.
The painting The Third of May 1808 depicts a tragic event about Napoleon's French soldiers vengefully slaughtering unarmed Spanish civilians when the Spaniards rebelled against their invasion in 1808.
