A complex geometrical patron, sometimes known as “Vesica Piscis”. In its simplest form, the Vesica Piscis is the overlap of two circles. Here many more circles have been drawn and words have been placed in the sections. The text is not easy to read, but they appear to be vices, both good and bad. The image comes from the “Grand Architecte” degree, the 24th in the French 1780’ies collection of degrees that were compressed to the French Rite.
