[tex-live] cheking available fonts Ancient Greek?

[Pau]

Hello,

I have this problem that I need a couple of paragraphs in Ancient
Greek in a very long document written in English, a book.

xelatex does the job but I have only managed to figure out a couple of
fonts for it to work with. For instance, Minion Pro will not work.

I am using now DejaVu Serif and Linux Libertine O because it has the
Ancient Greek option.

The problem is that the document is now written entirely in this new
font, which makes it much longer than the default
(\documentclass[a4paper,10pt,openright]{book}) and also that the
"Chapter" "Index" etc are now written in Ancient Greek.

Questions

(1) Which font is small and supports Ancient Greek?
(2) How to set back the "Chapter" etc to English?

Thanks

PS: Here is my header _is_ very complicated but I do not think that
this is the problem

This is my header now for including the few paragraphs in Ancient Greek:
