Andreani became well-known as a young painter for his artful replica of The Parnassus by Mantegna, already at the Louvre. Using Renaissance techniques he developed his own style trying to grasp the most intense aspects of an ever-changing reality. His production, rightly representative of 20th century art, alternates portraits of elegant ladies, of poor workmen, and city landscapes. Throughout his life he maintained a strong link with the city of Venice, inspired by the very particular atmosphere of the lagoon city. Painting the facade of saint Mark for instance, Andreani was attracted by the possibility to synthesise the monumental beauty of the church, depicting it on a bright day, with elongated shadows that seem to fragment the paved floor in front of the church. It is yet another attempt to grasp the elusive magic of the Serenissima.
