In November 1553, Dr Stephan Edwards discovered two letters written in London in July 1553 that mention Lady Jane Grey. He writes that, ‘To my knowledge, neither of these letters has ever been published in English, and no historian writing on the subject of Jane Grey or the succession dispute of 1553 has ever cited them. They are presented here for what I believe is the first time in the modern era.’ (Some Grey Matter )
The letters appear in the third volume of ‘Lettere di Principi’ a series of ‘a collection of letters to, from, or about a wide variety of early-sixteenth-century European rulers, noblemen, and princes of the Roman Catholic Church’ (Some Grey Matter ), which was published, in 1577 by Giordano Ziletti. According to Edwards, the author and recipient of the letters are unknown but he thinks that they were written by a member of the Venetian diplomatic embassy.
