The problem (see below) is solved by removing 3 lines
\usetypescript[lmodern][\defaultencoding]
\starttypescript[serif][default][size]
\stoptypescript
But I introduced these lines because, some time ago, I read in some
manual that to get hanging punctuation and so forth
The problem is that I no longer seem to be able to produce footnotes
when the bodyfont is Latin Modern and I am using the Thomas Schmitz’
ancientgreek module.
The following works but only when the two lines installing the
ancientgreek module are commented out.
