when did we start putting shoes on horses
Horseshoe Historians differ on the origin of the horseshoe.[6] Because iron was a valuable commodity, and any worn out items were generally reforged and reused, it is difficult to locate clear archaeological evidence.[7] Although some credit the Druids, there is no hard evidence to support this claim.[6] In 1897 four bronze horseshoes with what are apparently nail holes were found in an Etruscan tomb dated around 400 B.C.[8] The assertion by some historians that the Romans invented the "mule shoes" sometime after 100 BC is supported by a reference by Catullus who died in 54 BC.[6] However, these references to use of horseshoes and muleshoes in Rome, may have been to the "hipposandal"—leather boots, reinforced by an iron plate, rather than to nailed horseshoes.[9]
