Celtic Empire
Celts had a large reputation as head hunters, and were famous for putting victim’s heads on their chariots, and in front of their homes. Many Celts fought completely naked (much to the surprise of their enemies) and are famous for their iron long sword: “They cut off the heads of enemies slain in battle and attach them to the necks of their horses. The blood-stained spoils they hand over to their attendants and striking up a paean and singing a song of victory; and they nail up these first fruits upon their houses, just as do those who lay low wild animals in certain kinds of hunting. They embalm in cedar oil the heads of the most distinguished enemies, and preserve them carefully in a chest, and display them with pride to strangers, saying that for this head one of their ancestors, or his father, or the man himself, refused the offer of a large sum of money. They say that some of them boast that they refused the weight of the head in gold.
