Sundial of Baelo Claudia

Baelo Claudia (Bolonia, Cádiz)
1st century AD


This sundial was situated in the forum, or in a place very close to it, in the town of Baelo Claudia. The spherical sundial is a conical projection of the celestial sphere. Three transversal lines represent the sun’s path during the equinoxes and the winter and summer solstices. Eleven longitudinal lines indicate the hour circles, which divide the equinoctial line into 12 identical spaces.


This section contains objects associated with different aspects of the Roman presence in the Iberian Peninsula, such as the language and laws of Rome, Roman technologies for public works, and the creation of an urban society, reflected most notably in the forum. Meanwhile, everyday objects used inside and outside the home offer an insight into the daily lives of Hispano-Roman men and women.
