The first mention of the statue was by German archaeologist Alfred Wiedemann in 1884 in his Ägyptische Geschichte: German: zwei Fragmente einer grossen Steinstatue sind gleichfalls erhalten geblieben [Im Besitz des Herrn Meuricoffre zu Neapel.]
In English: “two fragments of a large stone statue have also been preserved [owned by Mr. Meuricoffre at Naples.]”

In 1895, Weidemann published the Egyptian hieroglyphs: German: Vor nahezu 15 Jahren hatte ich Gelegenheit im Landhause des H. Bankier Meuricoffre zu Neapel eine grosse Statue aus hartem Sandstein des Koenigs Osorkon I kennen zu lernen.
Von ihr waren zwei Fragmente erhalten.
Zunaechst die Buste, an deren Brust vorn stand, am Guertel befand sich der Cartouchenrest, am Ruekenpfeiler.
Dann ein Theil der Basis mit darauf stehenden Fuss.
In English: “ Almost 15 years ago I had the opportunity to visit the country house of the banker Meuricoffre of Naples to get to know a large statue made of hard sandstone of King Osorkon I. Two fragments were preserved from it.
First the bust, on the chest of which stood at the front, on the belt there was the rest of the cartouches, and on the rock pillar.
Then a part of the base with the foot.”
