Sundial

Roman sundial, in which the equator line are drawn, the line of the summer solstice and five hour lines and a slit at the top where the gnomon was, made with an inclination of 6 ° to the main axis clock.

This element would be in a public space of the city and their orientation would be conducted in relation to this space, this rotation of the gnomon allow the orientation of this towards the geographic south. This variation of the gnomon respect to the axis could provide some clues to its location in the city thanks to the data on the planning of Castulo provided by Manuel Buess ("Urbanistische Untersuchungen mittels geophysikalischen Prospektionen in der iberisch-römischen Stadtanlage von Cástulo". Lizentiatsabschluss an der Universität Bern, 2009), where we find an urban orientation similar to the clock in the southwest of the city.
