The picture at the web site below is what I mean.
Although in this case that curved line is on the top whereas I have
usually seen it on the bottom.
Does this symbol have a specific name and also when do you use it on
the top and when do you use it on the bottom?
I think that dingbat might have been called a Dwiggin, named after a
designer who created many dingbat designs. Just a guess, something
that comes to mind from a long time ago......
I guess my question is if there is a formal name for this category of
symbols. I realize dingbat is where you can find them but I was
wondering since the symbol seemed to have been around before the
computer is there a name for this kind of symbol and when are you
supposed to use it?
Generally they're ornaments. More specifically, ornaments designed for
the top of a page are headpieces and those designed for the bottom are
tailpieces. They are usually parts of sets that include borders (which,
in turn, include corner pieces) and fleurons (the last generally taken
to be ornaments with a floral motif rather than just a fancy curve).
