This specialty Coffee mug is engraved with our original Celtic Dragon Design. The dragon is a common thread throughout much of humanity's lore. For the Celts and Norse, the dragon is believed to be the most powerful of creatures, often comparable to forces of nature, and was the companion of different gods and goddesses. Centuries later the dragon is still found as a common heraldic theme as supporters or as the centerpiece, as seen on the Welsh Flag. The dragon is also found on the Coat of Arms and Clan Crests of many families originating from nations with Celtic roots (i.e. Scottish Clans Seton and Somerville or Irish family Drake). *Our Coffee mugs offer a thick solid glass base and sturdy walls, creating a pleasing tactile experience and trustworthy weight.
