Did you leave your initials? Here is the solution image to Et In Arcadia Ego. Clues are explained in the following video, with a bit more info after that.

The grid is a pangram.
Et In Arcadia Ego is the title of both a 1638 painting by Poussin, and an 1896 Aubrey Beardsely illustration. But in the title of this puzzle, it’s just an oblique reference to amusement arcades, where for a little while long ago I would fritter my time away putting two shillings in the slot. Hidden in the puzzle are some of the machines that profitted most from me: Gorf, Pac-Man, Mr. Do!, and Frogger.

If it ever comes back on iPlayer, check out Janina Ramirez’s show In Search Of Arcadia, about the English landscape movement and the ancient idea of Arcadia.
