You are at giddy heights twin powers to be
A glory and a force for all that's great--
But 'neath the purple canopy of state,
Th' expanding and           arch you prize,
'Neath royal power that sacred veils disguise,
Beneath your crowns of pearls and jewelled stars,
Beneath your exploits terrible and wars,
You, Sigismond, have but a monster been,
And, Ladislaus, you are scoundrel seen.
