On a gravestone next to William Wordsworth's in Grasmere I once saw
written in chalk "Here lies Fred, Who was alive and is now dead".
On the side of the house in an unadopted street in Edinburgh where David
Hume lived (Hume "the atheist") a lady friend chalked "St David St".
Hume left it there because it tickled his fancy. Shortly afterwards a
council official came round replacing all worn and missing street signs,
and that street became officially known as "St David Street".
"There is a story (which you won't understand unless like Bede, you have
learnt Latin) that soon after his death, one of his pupils sat down to
compose an epitaph for his tomb. He had written as far as this--
Hac sunt in fossa
Bedae ossa
Here are in this tomb
Bede's bones
but he could not think of a word that would fit into the line, for a
word like sancti (saint) would have spoilt the metre. And so, much
troubled, he got him to bed. Next morning he went to his task again, and
found that an angel had put in the word that was wanted--
Hac sunt in fossa
Bedae Venerabilis ossa.
Here are in this tomb
Bede the Venerable's bones.
So this saint has ever since been known as the Venerable Bede."

P.S. Perhaps the outcome of a hexameter line was pure accident?!?
