The so-called horn of Saint Cornelius in the romanesque church of St. Severin in Cologne, originally a drinking-horn, refurbished around the year 1500 as reliquary for several saints, including Saint Cornelius, Saint Cyprian, and the remains of Saint Ursula and her 11.000 virgin martyrs. It's exhibited in Museum Schnütgen in 2016 for a period of 2 months during renovation works in the church.
