The "Papal Aggression" generated sermons, tracts, novels...and, alas, poetry. Someone writing under the pseudonym "Pyraxius" decided to perpetrate The Martyr's Memorial (1851), which contains such sublime stanzas as this:
And there were shouts of triumph on that day!
And ROME exulted in her feast of blood!
So the fierce Vulture rends her panting prey,
And piecemeal mangles in delirious mood!
The Gate Flaminian and the Appian Way
Rang with tumultuous rapture; while the brood
Of bloodstain'd worshippers at PETER'S SHRINE
Crown'd with sweet-incens'd prayers the holocaust
Not one of the more pro-Catholic poems of the nineteenth century, just in case you were wondering.
I keep thinking that I should write an article about this material. And yet, somehow, I have managed to refrain.
