Absent outer half of eyebrows

The Sutton Hoo helmet is an ornately decorated Anglo-Saxon helmet found during a 1939 excavation of the Sutton Hoo ship-burial. It was buried around 625 and is widely believed to have belonged to King Rædwald of East Anglia; its elaborate decoration may have given it a secondary function akin to a crown. [Source: Wikipedia ]
