How can I make a footnote to a footnote? E.g.,
Playfair's axiom\footnote{so called in honor of mathematician John Playfair, etc, etc., but was actually discovered by Proclus\footnote{Greek mathematician, etc, etc.}}

\footnotetext{Greek mathematician, etc, etc.}
But I'd advise against doing this.
As a bonus, here's an example of how you can really mess with footnotes.
\documentclass{article}
\begin{document}
\footnotetext[4]{We have to go back to the future, Marty!}
Foo\footnote{The footnote to this sentence is true\footnotemark}
\footnotetext{The footnote to this sentence is false\footnotemark[1]}
more body text\footnotetext[42]{This footnote doesn't appear in the main text}
And more body text\footnote{And we're back to the normal numbering.}
But look where this footnote text ends up!\footnotemark
\end{document}
A few points.
\footnotemark
s appear in the text.\footnotemark
and \footnotetext
give you control over what number actually appears. (Useful for repeating a footnote if it is relevant again later.\label
and \ref
Body text:
Footnotes:
\footnotemark[<num>]
and \footnotetext[<num>]{<text>}
, since it actually allows overriding of the mark used in the footnote.
Use the bigfoot
package (as I suggested in the above comment). E.g.:
\documentclass{article}
\usepackage{bigfoot}
\DeclareNewFootnote{Default}
\DeclareNewFootnote{B}[alph]
\MakeSortedPerPage{B}% perhaps also useful to know about

\footnotemark
and\footnotetext
trickery should do it, but like @Seamus I would do it.bigfoot
does this (example given in the manual). It is not a normal need, but critical editions which themselves include a scholarly apparatus may make such a situation necessary.
