Gauden, raking up material from all quarters, had inserted in his
compilation a prayer taken from the _Arcadia_. Milton mercilessly
works this topic against his adversary. It is surprising that this
plagiarism from so well-known a book as the _Arcadia_ should not have
opened Milton's eyes to the unauthentic character of the _Eikon_. He
alludes, indeed, to a suspicion which was abroad that one of the royal
chaplains was a secret coadjutor. But he knew nothing of Gauden at the
time of writing the _Eikonoklastes_, and probably he never came to
know anything. The secret of the authorship of the _Eikon_ was well
kept, being known only to a very few persons--the two royal brothers,
Bishop Morley, the Earl of Bristol, and Clarendon. These were all safe
men, and Gauden was not likely to proclaim himself an impostor. He
pleaded his authorship, however, as a claim to preferment at the
Restoration, when the church spoils came to be partitioned among
the conquerors, and he received the bishopric of Exeter. A
bishopric--because less than the highest preferment could not
be offered to one whose pen had done such signal service; and
Exeter--because the poorest see (then valued at 500 l. a year) was good
enough for a man who had taken the covenant and complied with the
usurping government. By ceaseless importunity the author of the _Eikon
Basilike_ obtained afterwards the see of Worcester, while the portion
of the author of _Eikonoklastes_ was poverty, infamy, and calumny. A
century after Milton's death it was safe for the most popular writer
of the day to say that the prayer from the _Arcadia_ had been
interpolated in the _Eikon_ by Milton himself, and then by him charged
upon the King as a plagiarism (Johnson, _Lives of the Poets_.)
