Where is this 'memento mori'?

'Memento mori' essentially means 'reminder of death' in Latin. A skull, skeleton and hourglass are typically used as such, for rather apparent reasons. The skeleton in the image is about to cut a 'thread of life'. This loosely alludes to the ancient Greco-Roman mythical three 'Fates', who weave, measure then cut every individual persons' 'threads of life'.

The two figures are part of an epitaph in the church of St. John Nepomuk in Munich, more popularly known as 'Asamkirche' because the two Asam brothers did most of the decorative work. Cosmas Damian (1686-1739) was primarily a painter while Egid Quirin (EQ,1692-1750) a sculptor; however, both were also stuccoists. The epitaph was a later addition, mounted after both Asam brothers died, honoring a parishioner who died young, a certain Baron Johann Nepomuk Joseph von Zech (1732-1757), a namesake of the church's dedicatee. It was executed by Franz Ignaz Günther (1725-1775), whose style is Rococo while that of the Asam brothers is late Baroque. Like EQ Asam, Günther was also a sculptor of life-size and smaller figures, usually either with wood or stucco and mostly for church decoration. Günther did the majority of his work in Munich and more or less within a 100-mile radius thereof.
