Freemason's apron

A long semicircle of deerskin, with a folded triangle application at the top. There is a coloured etching on the leather triangle, showing a winged angel head placed in the middle of rays and clouds. An identical, but smaller motif is repeated under the triangle. The semicircle of the apron shows a Corinthian column on the right and left, under a cloudy sky with moon crescent. There is a domed building with columns in the middle. The column on the right of the building shows the letter J, while the left one has the letter B, with a checkered floor, shown in perspectives, in between. There is a shorter column on each side. In the foreground, we can be discerned the emblems of the freemasons: measuring tools, compasses, torch, sword, book, a scroll of paper and a hive.
