This monument isn't directly over Gray's tomb, but it's in the same churchyard. In case you can't read the fine print, here's what it says:
"Beneath those rugged elms, that yew-tree's shade,
Where heaves the turf in many a mould'ring heap,
Each in his narrow cell for ever laid,
The rude forefathers of the hamlet sleep.
The boast of heraldry, the pomp of pow'r,
And all that beauty, all that wealth e'er gave,
Awaits alike th' inevitable hour.
The paths of glory lead but to the grave." (lines 12-15 and 33-36)
