Giambattista Bodoni (1740-1813) Bodoni, the quintessential Italian font, is widely used to this day. Bodoni himself was born in Piedmont, where Eco hales from, and Eco's grandfather was a typographer.There's even a sample of what it looks like (scroll down to "Page 8").
I love this sort of thing. I once listed possible literary allusions in all of the songs of a favorite band of mine.
I'll be keeping tabs on this endeavor.
