I was on the Sacred Way in Ephesus, one of the great cities of the ancient world, on Turkey’s western coast. One marble column had the jolly line “Ἀγαθὴ τύχη” – “Good luck”. Suddenly, all those years spent learning Greek vocabulary at Westminster School clicked into super-sharp focus.

Those two words are simple enough – but what a lot of useful baggage they carried. I remembered my old Greek teacher telling me that agathos (“good”) is behind the name Agatha – literally “good girl”. I remember, too, him teaching that agathos meant “brave”.
