Greeks did use butter, but not milk. But Illyrians, (northern neighbors, in modern day Albania) did drink milk. At some point they were invaded/incorporated by the Roman empire, and about 190 B.c. 'drinking milk' was not such a unfathomed thing. (but, albeit, might have been not a 'aristocratic' thing to do). http://www.ancientportsantiques.com/wp-content/uploads/Documents/PLACES/Adriatic/Illyrians-Wilkes1996.pdf http://www.ancientportsantiques.com/wp-content/uploads/Docum... So, romans didn't drink milk originally, but their neighbors across the sea did.
