The triscele is commonly found in late Celtic art and is thought to have some Roman influence, although fine examples are found in the native art of Ireland and Scotland. It is thought to represent the three realms of Celtic lore: the past, the present and the future. One of the most popular of Ancient Celtic designs, it survived well into the Christian period, probably because it could also be considered to represent the Holy Trinity.
The quaich (pronounced quake from the Gaelic word cuach) is a shallow drinking cup that has a rich heritage in Scotland - indeed it is a uniquely Scottish invention, having no apparent connection to any other European drinking vessel. Traditionally used in Scotland to celebrate a bond between two clans, it was also used in the 17th century to offer welcome to travellers and is now commonly used in wedding and christening ceremonies.
The quaich also hails from medieval times when people were very distrustful of strangers and therefore carried their own cup for fear of either poisoning or worse yet.. the watering down of their whisky!
