Sundial on garden armillary sphere

This handcrafted corten steel sundial is able to show the three-dimensional representation of the real celestial vault, its orientation and its axis of rotation. The main meridians, the circle of the celestial equator, the arcs of the solstices and the poles are represented in the sphere. For this model, corten steel was used in order to also use the oxidation of the material to express the passage of time.
