Painted during the latter part of Giotto's career, the Madonna and Child was the central part of a five-section polyptych, or altarpiece in many panels (see Reconstruction). Giotto utilized a conservative Byzantine-style background in gold leaf, symbolizing the realm of heaven, and included a white rose, the traditional symbol of Mary's purity as well as a reference to the innocence lost through Original Sin. Yet, the Madonna and Child introduces a new naturalistic trend in painting. Instead of making the blessing gesture of a philosopher, the infant Christ grasps his mother's left index finger in a typically baby-like way as he playfully reaches for the flower that she holds.
