Unknown perpetrators severely damaged a sculpture that was part of artist Nicole Eisenman’s site-specific installation Sketch for a Fountain, at Skulptur Projekte Münster, sometime between Wednesday, July 19, and Thursday, July 20.

According to exhibition officials, vandals beheaded the sculpture of a larger than life-size figure reclining on the ground in front of a rectangular fountain. The head is still missing. The four other figures installed in various positions—sitting, lying down, and standing—in and around the basin were left alone.

After Eisenman was informed of the incident, she decided that the best course of action is to repair the sculpture’s damaged area. The figure will remain a part of the ensemble, but the head will not be reconstructed. The artist will work with the exhibition’s curatorial team to complete the necessary repairs by the end of the day.

Shortly after the decennial opened in June, thieves targeted Harsh Citation, Harsh Pastoral, Harsh Münster, 2017, an installation by Japanese American artist Ei Arakawa. According to police, the perpetrators stole the LED painting of the Jutta Koether work, which was encased in a glass vitrine as part of Arakawa’s piece.
