29. Sixtus V's Master Plan of Rome, 1589. This fresco in the Vatican Library is oriented from northwest to southeast. Medieval Rome and the Vatican are both cut away by the arch of the Library door, so that the view is concentrated upon the undertakings of Sixtus V. The picture is dominated by the straight line of the Strada Felice which runs from the Piazza del Popolo on the left, past S. Trinità dei Monti to S. Maria Maggiore and then further on to the Lateran. Obelisks and columns project from their squares, and the fountains of the Acqua Felice can also be seen in the middle distance to the left, on the Strada Pia.

Figure 5.22 — Rome, a section of Nolli's plan of 1748, between the Tiber and the Piazza Navona (north at the top). This area of low-lying ground was part of the ancient Campus Martius, which is believed to have consisted of a number of formally planned, if unrelated, parts and to have included many of the city's latter day architectural monuments.

Haphazard conversion and rebuilding resulted in a typical mediaeval form; many ancient remains being incorporated into later buildings. The Piazza Navona, top centre, follows exactly the shape of the central area of the Emperor Domitian's stadium (AD 81-96) with seats and corridors incorporated into the foundations of the surrounding buildings (see page 131).

76. Piazza del Popolo, Rome. Engraving by Tempesta, 1593. The Porta del Popolo, the Renaissance church of Santa Maria del Popolo, the obelisk, and the gardens of the Pincio.

77. Piazza del Popolo, Rome. View toward the twin churches of Rainaldi.
