The Dial from the ‘Palais Farnèse’: Roman or Modern?

This article investigates a spherical sundial in the 'Palais Farnèse', Rome, questioning its Roman origin due to its perfect state of conservation and lack of gnomon hole. It hypothesises the dial is an 18th or 19th-century copy of a Roman original, potentially with a symbolic rather than functional purpose related to the palace's 'Trophées Farnèse' compositions about Time.

Mapping Greco-Roman Sundials Using GIS

This article details a project to map over 500 excavated Greco-Roman sundials across the Roman Empire using GIS. It describes georeferencing historical maps, digitising province boundaries, and creating a database to display sundials by location, type, shape, and period, thereby analysing them in their geographic context.
