[1] A model of this ship, placed in 1840, can be seen in St. Jørgensbjerg Kirke[2][3] in Roskilde HDMS Bellona was launched on 15 September 1830.

She was under the command of captain Louis de Coninck and brought back some of Bertel Thorvaldsen's works.

[1] The primary purpose of this voyage was the establishment of trade agreements with the South American states, but also to establish contact to emigrated Danish citizens and in general fly the Danish flag in the new world.

Scientific expeditions were also in fashion (not the least the recently completed voyage of HMS Beagle 1831-36 with Charles Darwin on board) and the Danish King Christian VIII had a keen interest for natural sciences.

Almost nothing is known from direct sources about Krøyer's work on Bellona, but indirectly from his later scientific publications it is evident that he collected a wealth of animals, in particular crustaceans.
