When I study Latin I have many times been asked if I also study Greek. When my paternal grandfather studied at the university about 80 years ago he had studied both Latin and Greek. Still today people tend to study both classical languages. Why is this? During the Middle Ages people in western Catholic Europe could not Greek. In the Byzantine Empire people could Greek but not Latin. So I wonder now do I have to study Greek? I am very interested in the Latin language and Roman litterature. I am not so interested in Greek. What do you think? Has Greek effected Latin much?
