Um, indents came quickly after printing though they were possible
before, in manuscripts. Most important sections (grafs) would be
marked off with a large Versal letter, usually ornamental. The
illuminator was helped in most cases by the device of a body-text
letter in a large space allotted to the Versal.
If the illuminator didn't get to a page (perhaps before deadline),
the page would go unfinished.
With a great increase on the number of versals needed in a printed
edition, many simply wouldn't be put in, and the large space was left
Economics being economics, and even with the huge number of scribes
and illuminators cast into the art-bin of history, the habit never
returned of setting the paragraph off with a versal, and the
paragraph indent soon became standard.
