The tore (torques), or cord of gold worn round the neck, was introduced from Gaul.
It has yielded four bronze swords, ten socketed spear-heads, forty celts or axe-heads and sickles, fifty knives, twenty socketed chisels, four hammers and an anvil, sixty rings for the arms and legs, several highly ornate torques or twisted neck rings, and upwards of two hundred hair pins of various sizes up to 16 in.
Indeed the profusion of articles of gold which have been found is remarkable; in the Dublin Museum may be seen bracelets, armlets, finger-rings, torques, crescents, gorgets, necklets, fibulae and diadems, all of solid gold and most exquisite workmanship.
