⚠This page is a verso or flyleaf exhibiting severe ink bleed-through from the title page on the reverse (recto) side. Most of the legible text is mirrored. The original surface contains faint library stamps and a heavily obscured/cancelled inscription.

The following text is mirrored, visible only because the ink from the title page has bled through the paper over the centuries:

Pietro Galatino’s Work on the Secrets

of Catholic Truth

[Two lines of text, heavily cancelled with dark ink] ?

This was likely a handwritten note by a previous owner or a dedication. It has been deliberately obscured with thick ink, possibly by a censor or a later librarian to hide a name that had fallen into disrepute.

[Multiple faint circular library stamps or archive marks] ?

These stamps represent the book's journey through various libraries. Based on the previous page, these likely include the National Library "Vittorio Emanuele" in Rome and other institutional collections.
