Forma Urbis Romae
From Wikipedia, the free encyclopedia
The Forma Urbis Romae or Severan Marble Plan is a massive marble map of ancient Rome, created under the emperor Septimius Severus between 203 and 211. It originally measured 18 m (60 ft) wide by 13 m (45 ft) high and was carved into 150 marble slabs mounted on an interior wall of the Temple of Peace.
Created at a scale of approximately 1 to 240, the map was detailed enough to show the floor plans of nearly every temple, bath, and insula in the central Roman city. The boundaries of the plan were decided based on the available space on the marble, instead of by geographical or political borders as modern maps usually are.
The Plan was gradually destroyed during the Middle Ages, with the marble stones being used as building materials or for making lime. About 10% of the original surface area of the plan has since been recovered, in the form of over one thousand marble fragments.
[edit] Projects
Piecing together the surviving fragments of the plan is an activity that has engrossed scholars for centuries. Renaissance scholars managed to match and identify around 250 of the pieces, usually by recognizing famous landmarks such as the Colosseum and the Circus Maximus.
Recently, however, a project at Stanford University is digitizing the fragments and using computer algorithms in an attempt to reassemble more of the map.
