Giovanni Muzzioli (10 February 1854 – 5 August 1894) was an Italian painter.
Muzzioli was born in Modena after his family had moved from Castelvetro. From the time that he began to attend the local academy at the age of thirteen he was recognized as a prodigy, and four years later, by the unanimous vote of the judges, he gained the Poletti scholarship entitling him to four years residence in Rome and Florence. After his return to Modena, Muzzioli visited the Paris Exhibition, and there came under the influence of Sir Lawrence Alma-Tadema. His first important picture was In the Temple of Bacchus (1881); and his masterpiece, The Funeral of Britannicus, was one of the chief successes of the Bologna, Exhibition of 1888. From 1878 to his death (1894) Muzzioli lived in Florence, where he painted the altarpiece for the church of Castelvetro.[1]
