Michelangelo's David (1501-1504) at the Galleria dell'Accademia in Florence stands 5.17 metres tall. It was carved from a single block of Carrara marble that two previous sculptors had abandoned. When it was unveiled in Piazza della Signoria, contemporaries wept — it was considered a divine miracle in marble.
