Doubt about Shakespeare
"For God's sake, let us sit upon the ground
And tell sad stories of the death of kings;
How some have been deposed; some slain in war,
Some haunted by the ghosts they have deposed;
Some poison'd by their wives: some sleeping kill'd;
All murder'd: for within the hollow crown
That rounds the mortal temples of a king
Keeps Death his court and there the antic sits,
Scoffing his state and grinning at his pomp..."
What does "antic" mean there?
