It has eight vertical sundials with pin gnomons. The most famous Roman sundial was likely the large horizontal azimuth dial in Rome which used an Egyptian obelisk for a gnomon. Romans also used altitude dials, including the pillar dial. ------------------------
Dear Sara I understand that you are meaning the Augustus' sundial. If it is so, I would point out that it is already clear for many scholars that that dial was not a sundial but only a meridian line. The idea of the azimuthal shape maybe is from a 18th or 17th century engraving, but it is a fantasy figure, of course. Mario
