This is a memorial plaque in Vienna. It shows a former city judge and mayor of the town “Gross-Jedlersdorf” (today the 21st district of Vienna called “Floridsdorf”) called “Ignaz Bernreiter”.
Here is the text underneath the relief:
Bürgermeister, Ortsrichter [translation: mayor, city judge] Ignaz Bernreiter 1848–1864 1867–1869 Gross-Jedlersdorf
In his right hand he holds a staff. Given his duty I would define this as a judges staff. His left hand is rested on something I can’t define. It seems to be a shield with an emblem (escutcheon?), maybe showing an acorn, which I guess is a symbol for steadfastness. He also wears a prominent hat and a collar, but I don’t know if they have a meaning or are just decorative elements. The collar could represent his wealth.
As you see, there are a lot of maybes in my definition, as I am just not familiar with this topic. Maybe someone could clarify this for me. Thank you!
