Thousands of years ago in Ancient Greece, it was a commonly held belief that the gods walked the earth among us humans.
And that perhaps even Zeus himself might show up at your doorstep disguised as a vagabond.
From this sprang the legendary sense of Greek hospitality, known as ‘xenia’.
It meant that a complete stranger could walk into your home unannounced, and you had an obligation as the host to take care of him.
