106A Project of Porta Pia

This project is part of drawings series, having as their object the city gates, that Michelangelo carried out on Pio IV’s commission. Such in the Casa Buonarroti’s sheet 102 A, this drawing shows one of the version of Porta Pia and it was realised between the spring and the summer of 1561. The gate, several times elaborated with frenetical overlapping sketches that reflects various design ideas, shows the Michelangelo’s way to proceed. The artist used a sheet already used to investigate some figures, still visible on both sides.
