The Tournai Font from Tournai, Belgium dated to the Mid 12th Century on display at Winchester Cathedral in Winchester, England
The font is made from Tournai marble in Belgium and depicts scenes from the Miracles of St Nicholas of Myra on it's four sides. It was thought to have been commissioned by Bishop Henry of Blois in Belgium and shipped out to England in parts to be assembled upon arrival. The font is still used today for baptisms and Winchester Cathedral.
Henry of Blois was the younger brother of Stephen of Blois the king of England from 1135 to 1154. Despite his brother being king he initially supported the Holy Roman Empress Matilda during the Anarchy. However he later changed sides to support his brother and led a successful defence of Winchester from the Empresses forces.
