An amazing larger set in the main theme, and then a Play and Give of Alexander the Great
Upon considered reflection I am going to cavil at this. I would say that the main theme so far has been entirely mythological - even Achilles and Patroclus, though quite likely based ultimately on real people, have no concrete historical reality - whereas both of these sets bring us firmly into recorded history. The big set is of course the Battle of Thermopylae, famous from the movie, and a pretty securely dated event, as is Alexander's life.
Overall a truly wonderful sign, and a big thank you from me to all the Greek people whose sustained demand for such sets has brought us so many wonders. σας ευχαριστώ!
