[2] Baron's first printed work, "Eροτοπαιγνιον [Erotopaignion], or the Cyprian Academy," is dated from "my chambers in Gray's Inn, 1 April 1647."
Whole passages of the "Cyprian Academy" and of Baron's other works are taken, scarcely altered, from the 1645 Poems of John Milton, who was little-known at that time.
In an address to the reader, Baron acknowledges that the story is the same as that of Sir John Denham's Sophy, but adds: "I had finished three compleat acts of this tragedy before I saw that, nor was I then discouraged from proceeding."
In 1649 appeared "Apologie for Paris for rejecting of Juno and Pallas and presenting of Ate's Golden Ball to Venus."
He also states that Baron "is the first author taken notice of by Phillips in his Theatrum Poetarum, or his transcriber, Mr. Winstanley, in his Lives of the English Poets; and though neither of them give any other account of our author but what they collected from my former catalogue, printed 1680, yet, through a mistake in the method of that catalogue, they have ascrib'd many anonymous plays to the foregoing writers, which belonged not to them."
