Life and career
The orb, sceptre, and anointing horn, which are part of the Norwegian Royal Regalia, were commissioned by King Charles John and made by Zethelius in Stockholm for the King's coronation as King of Norway in 1818. Works by Zethelius are also exhibited at Nationalmuseum and Hallwyl Palace in Stockholm.

Zethelius acquired the manor house Nyby, near Torshälla, from his father-in-law Eric Nordewall, and in 1829 he founded the ironworks Nyby bruk on the site. Zethelius had the manor house of Surahammars herrgård constructed 1856–1858.
