The image on this page is a mirrored ghost image caused by bleed-through from the reverse side. The ink from the architectural title page has soaked through the paper, making the text and figures appear faint and reversed.
A faint, mirrored architectural frame is visible. At the top is an ornate arch decorated with a pediment. Two allegorical figures stand on the left and right sides of the frame. In the center foreground, a seated figure holds a large cross in their right arm and an open book in their left hand. The text in the center is mirrored and mostly illegible because the ink has bled through from the other side of the leaf.
frontispiece: an illustration facing the title page of a book, or the title page itself when it includes an elaborate engraving.
bleed-through: a condition in old books where ink from one side of a page seeps through the paper fibers and becomes visible on the opposite side.
