Product title: Irish Harp bone china mug - Irish gift designed in Galway Ireland
Product description: An Irish house always has a constant stream of tea being made in the kitchen. Therefore it's very important to have your own perfect cup. We have a selection of beautifully made Bone China cups. This collection of Irish Weave Mugs are beautifully illustrated. The harp has been a political emblem in Ireland for generations. The origins of its usage has unfortunately been lost but through oral and written traditions but we know of its presence from at least the sixth century AD. Even Brian Boru (941-1014AD), High King of Ireland, played this exquisite instrument just as all the gentry did during the Gaelic Lordship of Ireland which ended in 1607. The harp is the emblem currently used on such things as our coins, the flag on the Leinster flag and is the emblem of Guinness Black Stout. Therefore there is no denying the omnipresence of this elegant icon throughout Irish politics and history. The print is written in Irish script style similar to that in the famous Book of Kells. Further similarities to this are the colours of the border and the Celtic Knotwork patterns. This mug is so beautiful it could easily be used in a display case. It is also ideal for holding your perfect cup of tea.
