The Trundholm site refers to a single artifact pulled out of a Danish bog near Sjælland in 1902; but what an artifact! The object is a 23-inch long bronze wheeled statue of a horse pulling the sun.
Dated to the early Bronze Age on the basis of stylistic elements, the horse is hollow-cast and is one of the earliest representations of a horse in Europe. The sun is made of two disks, ornamented with intricate decorations in concentric circles. Anders Söderberg created a replica for the 100th anniversary of its discovery, which can be seen on the related link in the side bar.
