The latest issue of the Hoefler & Co. newsletter featured a couple articles from several years ago. Of note, this one about the ¶ character:
Like most punctuation, the paragraph mark (or pilcrow) has an exotic history. … in its original form, the mark was an open C crossed by a vertical line or two, a scribal abbreviation for capitulum, the Latin word for ‘chapter.’
I make liberal use of the capitulum on this site. I’ve adopted its meaning as a chapter marker and use it to mark the end of entries. It’s also linked to the permanent address of the item, conflating its appearance as a P.
I really just chose it because Heldane has a quite fetching rendition of the symbol. Aesthetics over semantics; you will hopefully see fit to forgive me.
