Tower of the Winds (Horologion of Andronikos Kyrrhestes), Roman Agora, Athens: close-up of the marble freize that runs around the top of the tower

NOTES: This octagonal tower dates from the 1st century BC and was originally the 'Horolgion of Andronykos Kyrrhestes'. It served as a water clock until the 6th century. The sides of the tower indicate the eight points of the Athenian compass, and the eight winds associated with these points are represented allegorically on the marble frieze that runs around the tower.
