In 1850 Raadsig made the painting "Ingolf tager Island i besiddelse", depicting Ingólfr Arnarson, the first Norse settler of Iceland, newly arrived on the site of what would become Reykjavík, commanding his high seat pillars to be erected. The painting was made at the time when nationalist sentiment was rising in Iceland, a few years after the Icelanders" ancient general assembly, the Alþingi was re-established. Raadsig was, evidently, sympathetic to the Icelanders" aspiration to recover their historical heritage.
The painting is currently on public display at Viðeyjarstofa in Viðey (an island near Reykjavík), where a plaque explains that it was a gift to the City of Reykjavík from Eimskipafélag Íslands on the occasion of the 200th birthday of Reykjavík (1986).
