The Coat of Arms is a silver cross in a sky-blue field with a fiery red cross in the silver one. There are four shield bearers, Iceland's old guardian spirits mentioned in Heimskringla (A History of the Kings of Norway) by Snorri Sturluson: a bull on the left of the shield, a giant to the right, a bird of prey on the top left and a dragon on the top right. The shield rests on a slab of basalt.
In Heimskringla, Snorri Sturluson wrote about the time that Haraldur Gormsson (also called Haraldur bluetooth, abt 930-abt 985), then King of Denmark, harboured serious intensions of invading Iceland. He recruited a magician to reconoitre, who transformed himself into a whale and swam to Iceland.
First attemted landfall was Vopnafjörđur on the northeast coast, but down from the hills to the sea charged the local dragon, accompanied by serpents and lizards, to repulse the intruder. Similar hostile encounters were experienced elsewhere: a big bird, with a fjord-width wingspan, protected Eyjafjörđur in the north; a snorting, raging bull and assorted spirits guarded Breiđafjörđur in the west; and a giant at Reykjanes in the southwest proved to be the clincher. Needless to say, the shattered scout swam back to Denmark and advised King Harald to lay off.
