The Picts are a tribe of ancient Britons who lived in North East and Central Scotland.
The Romans were unable to defeat the Picts, and this is one reason for the building of Hadrian's wall. One Roman legion is known to have went missing. The Picts have left on the landscape of Scotland echos of their rich culture, including intricate carved drawings of the various tribes, and a stone carved foot print of the king.
They are reported to have used lime to allow them to a spike up their hair. they are also reported to be painted. Most likely they were tattooed (using a blue dye made from woad) with tribal tattoos similar to their carved drawings. Proof of prehistoric tattoos exist with Ötzi the Iceman, a natural mummy found frozen in the Alps in 1991.
