The question was, however, not allowed to rest here. Cromwell wanted an authoritative decision, which would enable him to do more than merely protect individual Jews, and it was clear that this could not be obtained unless a more important person than Dormido were induced to take the matter in hand. The question had to be raised to a higher level, and for this purpose it was necessary that it should make some noise in the country. Only one European Jew had sufficient influence in England to stimulate the popular imagination, and to justify the Government in taking serious steps for the solution of the question. That man was the author of the “Hope of Israel.” In May 1655 it was decided to send Samuel ben Israel back to Amsterdam to lay the case before his father, and persuade him to come to London.[60] There is no mystery as to who suggested this step. Menasseh in his diplomatic way merely tells us he was informed that his “coming over would not be altogether unwelcome to His Highness the Lord Protector.”[61] There is, however, a letter extant from John Sadler to Richard Cromwell, written shortly after Oliver’s death, in which it is definitely stated that Menasseh was invited “by some letters of your late royall father.”[62] Sadler no doubt spoke from personal knowledge, for in 1654 he was acting as private secretary to the Protector, and the endorsement on Dormido’s petitions recommending them to the Council bears his signature.[63] Under these circumstances we can well understand that Menasseh was induced, as he says, to “conceive great hopes,” and that he resolved to undertake the journey. In October he arrived in London with the MS. of his famous “Humble Addresses” in his pocket.
