 One of the most famous "armes à enquérir" (often erroneously said to be the only example) was the Jerusalem cross said to have been chosen by Godfrey of Bouillon in 1099 (pre-heraldic and thus strictly speaking attributed arms) and later used by his brother Baldwin of Boulogne when he was made King of Jerusalem.These attributed arms of "Argent, a cross potent between four plain crosslets or", displayed five gold crosses on a silver field.A use of metal on metal is also seen on the Bishop's mitre in the arms of Andorra and in the arms of the county of Trøndelag in Norway, based on the arms of St. Olav as described in the Sagas of Snorri.
