Catholic theologians had employed for some generations past, as their best weapon against their adversaries. In these infamous productions, hatched by celibate pedants in the foul atmosphere of the Jesuit colleges, the gamut of charges always ranges from bad grammar to unnatural crime. The only circumstance which can be alleged in mitigation of the excesses of the _Regii sanguinis clamor_ is that Milton had provoked the onfall by his own violence. He who throws dirt must expect that dirt will be thrown back at him, and when it comes to mud-throwing, the blackguard has, as it is right that he should have, the best of it. The author of the _Clamor_ was Peter Du Moulin, a son of the celebrated French Calvinist preacher of the same name. The author not daring to entrust his pamphlet to an English press, had sent it over to Holland, where it was printed under the supervision of Alexander Morus. This Morus (More or Moir) was of Scottish parentage, but born (1616) at Castres, where his father was principal of the Protestant college. Morus fitted the _Clamor_ with a preface, in which Milton was further reviled, and styled a "monstrum horrendum, informe, ingens, cui lumen ademtum." The secret of the authorship was strictly kept, and Morus having been known to be concerned in the publication, was soon transformed in public belief into the author. So it was reported to Milton, and so Milton believed. He nursed his wrath, and took two years to meditate his blow. He caused inquiries to be made into Morus's antecedents. It happened that Morus's conduct had been wanting in discretion, especially in his relations with women. He had been equally imprudent in his utterances on some of the certainties of Calvinistic divinity. It was easy to collect any amount of evidence under both these heads. The system of kirk discipline offered a ready-made machinery of espionage and delation. The standing jest of the fifteenth century on the "governante" of the curé was replaced, in Calvinistic countries, by the anxiety of every minister to detect his brother minister in any intimacy upon which a scandalous construction could be put.
