No very serious consequences seem to have followed in this instance; but in the following year (1628), Henry Burton was charged by the same authorities with being the author of certain unlicensed books, _The Baiting of the Pope's Bull_, _Israel's Fast_, _Trial of Private Devotions_, _Conflicts and Comforts of Conscience_, _A Plea to an Appeal_, and _Seven Vials_. The first of these was licensed, but the remainder were not. They were said to have been printed by Michael Sparke and William Jones; Sparke was a bookseller, carrying on business at the sign of the Blue Bible, in Green Arbour, in little Old Bayley, and he employed William Jones to print for him. The parties were then warned to be careful, but on 2nd April 1629 Sparke was arrested and thrown into the Fleet, and with him, at the same time, were charged William Jones, Augustine Mathewes, printers, and Nathaniel Butter, printer and publisher. Butter's offence was the issuing of a newspaper or pamphlet called _The Reconciler_; Sparke was charged with causing to be printed another of Burton's works, entitled _Babel no Bethel_, and Spencer's _Musquil Unmasked_; while Augustine Mathewes was accused of printing, for Sparke, William Prynne's _Antithesis of the Church of England_. Each party put in an answer, and of these, Michael Sparke's is the most interesting. He declared that the decree of 1586 was contrary to Magna Charta, and an infringement of the liberties of the subject, and he refused to say who, beside Mathewes, had printed Prynne's book; it afterwards turned out to be William Turner of Oxford, who confessed to printing several other unlicensed books. A short term of imprisonment appears to have been the punishment inflicted on the parties in this instance. Both in 1630 and 1631 several other printers suffered imprisonment from the same cause, and Michael Sparke, who appears to have given out the work in most cases, was declared to be more refractory and offensive than ever.
