Addendum

Apologies for failure to blog for last three weeks.  I was co-teaching (with Jeremy Rau) a two-week seminar in Greek comparative grammar and Greek dialects.  In the course of preparing for that class I got my first good look at the volume A History of Ancient Greek:  From the Beginnings to Late Antiquity, edited by A.-F. Christidis with the assistance of Maria Arapoloulou and Maria Chriti. Cambridge: Cambridge University Press.   This book was first published in Greek in 2001 and translated by various hands in 2007.  Overall, the book is similar in conception to the Bakker volume, but more extensive (the first subsection on "the language phenomenon" seems out of place to me).  I have read only a fraction of the work, but some standout chapters are the ones by Claude Brixhe (History of the alphabet: Some guidelines for avoiding oversimplifications) and Julian Mendez Dosuna (on Doric and Aeolic).  Particularly relevant for Latin are the chapters on Greek and Latin contact by Robert Coleman and on evidence for Vulgar Latin from modern Greek dialects by N. Katsanis.
