Peter Nicolai Arbo (1831-1892) was a Norwegian painter known for his depictions of historical and mythological scenes. Born in Drammen, Norway, Arbo showed an early interest in art. After his education in Oslo, he continued his studies in Düsseldorf, where he became part of the Düsseldorf School of painting, which was known for its detailed and realistic depictions.

Arbo's works are characterized by their precise technique and ability to capture dramatic and emotional moments. His paintings are often inspired by Norse mythology and Norwegian history, which secured him a special place in Norwegian art history. 

Arbo was also active as a portrait painter, although it was his historical and mythological scenes that brought him the most recognition. His style is characterized by an academic rigour and a romantic sensibility that enabled him to vividly depict the epic qualities of the Norse saga world. Arbo's influence on Norwegian art and his contributions to the visual interpretation of Norse myths remain significant to this day. He died in Oslo in 1892, but left behind an impressive body of work that continues to be admired and studied.
