The Ballina treasure is a set of haxes and ingots discovered in 1940 in a gravel pit in Ballina , County Limerick, Ireland. It consists of fragments of three Roman silver vessels and four Roman silver double-headed ingots, three of which are stamped with inscriptions. The treasure has been dated to the late 4th or early 5th century. Several speculations have been made as to how this silver, which finds parallels in Kent, came to Ireland: as booty from an Irish raid on Britain, as part of a Roman payment to an Irish chief for keeping the peace, or as a payment or donation to Irish mercenaries or Federals .
