The Knights of Pythias complete manual and text-book ..
A manual and text-book for the Knights of Pythias fraternal order, written by John Van Valkenburg and published in Philadelphia by Moss & company in 1878 for members of the society. Its pictures are line-engraved emblems: a triangle inside a laurel-wreathed circle with keys and a lamp, a shield with an eye and a crest inside an oval wreath, a shield crossed by quill pens, and crossed swords within a wreath-bordered inverted triangle. A designer could take from them the interlocking triangle, wreath and shield motifs of nineteenth-century secret-society seals.
