martyr and patron of Oslo. The son of a noble landholder of Husaby (Norway), he spent his youth in Viking activities.
One day, crossing the Drammenfiord by boat, he was accosted by a woman who appealed to him to take her with him, as she was falsely accused of stealing and was in danger of death. Her pursuers then arrived and called on him peremptorily to give her up. He refused as he believed her to be innocent; whereupon they were both shot dead with a bow. Hallvard's body was thrown in the sea with a stone attached, but it floated: he was revered as a martyr for defending an innocent person. His body was enshrined in a stone church in Oslo, whose patron he became and still remains. Feast: 4 May.
