  Things get funnier, as there are two differents encodings for Ancient
Greek: the common “Babel” Greek, and an alternative one for Ibycus,
which has a separate pattern file (although it encodes exactly the same
information as far as I can see), and is a different language for Babel
Greek, called “Ibycus” (see language.iby.dat in TeX Live).

  And of course, there is Modern Greek, which comes in two flavours,
monotonic and polytonic; but they're really differences in spelling and
should have distinct hyphenation patterns.
