For All Hallows’ Eve, I present to you Jim Morrison’s gravestone, in Paris:
It appears that the tombstone with the Greek phrase was ordered by Jim’s father in 1990. In his retirement, his father studied ancient Greek in order to read the NT, as well as, clearly, to hone his epitaphographical skills. It is speculated that he might have intended a double meaning with the inscription. I suppose a modern idiomatic translation would be: “to the beat of a different drummer.” I could not find the phrase in any ancient text, but personally, it puts me in mind of Socrates, made unique by the guidance of his own δαιμων.
