Of course, there were a few problems in the version I posted which I have now corrected. They were in the first full paragraph on page 7 and fns. 16-17.

The marks from over a thousand supposed nailheads in the Catholicon (Mainz "1460") recently discovered by Paul Needham were, in fact, left by sand grains that fell on inked type and were crushed by the platen into the type. Revised article on this analysis at:

Found this woodcut in a sammelband at the Berlin Staatsbibliothek. No idea what's up, but the dude on the left seems to be hawking a fine vine and the Angel of Truth looks like he fell into a vat of leeches. Or maybe this involves poison ivy. c. 1474-5. LC copy on right has identical coloring.

I made some edits to the article, the most important of which address the possibility that the "nailheads" were caused by grain-sized pieces of type metal(?) that fell on the forme and were crushed into the type where they remained. These are highlighted in yellow. www.academia.edu/143660455/Th...

A stock phrase in #prescription drug disclosures is "Many people using this #medication do not have serious side effects." This seems to be saying "Most people taking this do have serious side effects." Is that meant to comfort you?
