How do I properly set up Calibre to automatically display Polytonic Greek characters?
I got this epub from the internet archive,
and it doesn't display any Greek at all. The pdf version under Foxit Reader,
for example, shows everything properly, then again it's an image scan of
the book pages.

epub (p.10.9 in Calibre):

I have given a complete analysis of the rhetorical treatise known under the
name of the 'PrjTopinrj ^09 'A\e%ai>$poi', a work long attributed to...

pdf (p.20 bottom page in Foxit):


Apparently, each epub has a CSS stylesheet which can be viewed when
browsing the content of the epub with an archiving soft like winrar.
Here it is:

body {
    font-family: "Palatino Linotype", "Book Antiqua", Palatino, Georgia, "Times New Roman", serif;
}
h1,h2,h3,h4 {
    font-family: "Palatino Linotype", "Book Antiqua", Palatino, Georgia, "Times New Roman", serif;
}
p {
    font-family: Georgia,  "Palatino Linotype", "Book Antiqua", Palatino, "Times New Roman", serif;
}
img {
    display: block; text-align: center; margin: 1em auto;
}

The default settings in Calibre has Times New Roman for serif and Verdana for sans.
I tried changing the serif to Palatino Linotype and the sans to Arial Unicode MS, but that
didn't do anything.

A different epub, which I got from this site but can't find the link, has 38 pages of
unicode text examples (greek, hebrew w. vowelization, latin lorem ipsum) and it displays
everything without me fiddling with anything.
This particular file has different folder with the embedded fonts, and one with
the stylesheet, but the Internet Archive's epub did not have a folder with the fonts.

I uploaded it to megaupload (although it is from these forums; just can't
find the link):

One thing that was odd about this file is that Times New Roman,
as well as some other fonts, despite being completely Polytonic Greek-enabled,
did not display the accented letters.

I'm sorry if this has been asked before. I've searched and couldn't
find a solution I understood.

Any help would be appreciated.
