Hezekiah (Ezekias) was king of Judah. He is described as a pious man who fought the Philistines.

In his right hand he holds a sundial. It is a reference to the story in 2 Kings 20, where Hezekiah is first miraculously cured and then receives a signal from God who makes the shadow on the sundial move in reverse direction.

This is one of the 43 windows in the cathedral that show Jesus' ancestors.
