Saint Alexius (right) in the company of St Rocus, St Sebestien and St Pirminius, mosaic. The painting on the façade of the church in Innsbruck, Austria, dates from the early 17th century. The church was erected to stop the plague epidemic in the city, which is why St. Rocus, who was venerated as a saint protecting against the plague, was added to the list of saints.
