[3] However, at the time, Prussian authorities, who were still nominally in charge of the city, would not approve the full construction of the monument.
[citation needed] The fall of Napoleon ended the existence of the Duchy of Warsaw, restoring full control of Thorn to the Prussian authorities and delaying the Thorn monument project and eventually forcing Staszic to change the venue to Warsaw, in the Russian part of Poland, where the monument designed by Bertel Thorvaldsen was completed in 1830.
[4] After the Napoleonic Wars, Thorn was made part of the Kingdom of Prussia, and local German citizens campaigned for and received the go-ahead for the monument that was eventually completed in that city in 1853.
The pedestal bears a Latin inscription drawn up by Alexander von Humboldt:[5][7] "Nicolaus Copernicus Thorunensis, terrae motor, solis caelique stator" ("Nicolaus Copernicus of Thorun, mover of the earth, stopper of the sun and heavens").
[3] Celebrations of the 150th anniversary of the monument were held on 25 October 2003, attended by the Marshal of the Sejm of the Republic of Poland, Marek Borowski.
