sundial. The direction of the restoration work was entrusted to the architect Giovanni Antinori, who restored the obelisk using granite from the Column of Antoninus Pius. This column's base, with its famous relief showing the Solar obelisk held as a symbol of the Campus Martius regio by a personification of the Campus, is still preserved in the Vatican Museums. In the new layout of Piazza Montecitorio (inaugurated on 7 June 1998), a new meridian was traced on the pavement in honor of Augustus's meridian, pointing towards the main entrance of the palazzo. Unfortunately, the shadow of the obelisk does not point precisely in that direction, and its gnomonic function is definitively lost.
