Mostly seen in Anglo-Saxon Freemasonry. This symbol has different meanings. It can sometimes be seen on first degree tracing boards, but he point within the circle is a third degree element in many rituals. With the two lines included, the symbol can refer to the year (circle) and the two solstices (where the circle and the lines touch), hence referring to the two patron saints of Freemasonry, Saint John the Evangelist and Saint John the Baptist.
