Unknown maker and mysterious symbolism.
Who is in the middle? A vague resemblance to Ferdinand I of Austria who was coronated in Prague 1836,but could be an ancient personality.
Left: Pegasus,the horse of Muses,liberated (broken chains),Lyre (music,poetry or art in general),grape keg (old Venetian word brenta) and unknown staff,wand,wooden crutch.
Right: Laurel wreath,thermometer (barometer),carpenter plane,scepter,crown among the snakes.
Help and ideas appreciated.
