To mark the bicentenary of the death of Giandomenico Tiepolo, a selection has been made of those drawings which document his activity in Venice - starting with the first independent works produced when, just over twenty years old, he received a commission to paint fourteen Stations of the Cross and thereafter other religious pictures for the church of San Polo. The preparatory drawings for these paintings, which Giandomenico would complete between 1747-1749, are also useful documents in studying the working methods adopted in the studio headed by Giambattista himself. Various studies were produced of individual details of a painting - particularly drapery and anatomical details such as feet and hands, which were most difficult to transpose into painting. This makes the exhibited drawings and studies for Saints Helen and Macarius find the True Cross especially significant as they form a sort of puzzle from which one can build up the final composition of the painting.
