Related to "Last is first", old Spanish books sometimes put at the end of the page the first syllable of the next page. (It was quite disconcerting when I first saw it.)
That's called a "catchword", and it's common in many older texts (not just in Spanish). It serves two purposes - it makes it easier for a person reading the book aloud to read smoothly while turning a page, and it makes it easier for bookbinders to spot pages which are missing or out of order. (Page numbers were, believe it or not, a later development.)
It was common throughout Europe in the early modern era.
I've got a book of recipes from Williamsburg, Virginia, a kind of outdoor museum LARPing as 1775. The recipes are from various sources, but they typeset it as a period document, including those catchwords. I find it charming.
