Ephesus is where Oz wants to go. It is on the Ionian coast in modern day Turkey. St. John was there in the first century. So too was St. Paul, but Oz would go back another 500 years.
He wants to stand before the Temple of Artemus, to gaze at the Library of Celsus. He wants to meander along the banks of the Kaystros River and put his foot in the ever-flowing water, as did Heraclitus of Ephesus in the 5th century before the Christian era.
Knowing there is no answer, he wants to ask:
To Heraclitus who knows,
To Heraclitus who says,
All things pass and nothing stays.
Could I not run ahead?
And stepping in the river,
Find the shoe I lost.
Heraclitus of Ephesus was really not so old, 60 years old to be precise when he died. Unless, one considers the average life expectancy in ancient Greece was 25, and that Heraclitus was wise beyond his years, having written on topics diverse as nature, logic, learning, and human affairs.
Then we may conclude that he lived to a ripe old age, having learned that all things pass and nothing stays.
