A general city plan with Dutch labels in which one small red symbol in the Campus Martius flags Caligula's amphitheatre.
The plan covers the whole walled city with the Tiber, the regions numbered in Roman numerals and landmarks such as the Palatine, the Forum and the Circus Maximus. The Amphitheatrum Caligulae appears only as a red mark north of the Capitoline, with no detail of the building itself.
