It is just conceivable that it is to some occasion in this campaign that Vaughan refers when he calls Dr. Powell his "fellow-prisoner" (vol. ii., p. 178). The poet may even have been the Captain Vaughan whose name appears in the official list of prisoners taken at Rowton Heath.[16] Powell's name is not there, but then the list does not profess to be complete. But on the whole I think that Vaughan and Powell were only fellow-prisoners in the Platonic sense of imprisonment in the flesh, and even if a literal imprisonment is intended, it may have been due to some act of persecution which Vaughan had to suffer as a Royalist at a later date. There is in _The Mount of Olives_ (1652) a _Prayer in Adversity and Troubles occasioned by our Enemies_ (Grosart, vol. iii., p. 75), which, if it is to be taken--I think it is not--as autobiographical, seems to show that, at least for a time, he lost his estate. The prayer runs: "Thou seest, O God, how furious and implacable mine enemies are: they have not only robbed me of that portion and provision which Thou hast graciously given me, but they have also washed their hands in the blood of my friends, my dearest and nearest relations. I know, O God, and I am daily taught by that disciple whom Thou didst love, that no murderer hath eternal life abiding in him. Keep me, therefore, O my God, from the guilt of blood, and suffer me not to stain my soul with the thoughts of recompense and vengeance, which is a branch of Thy great prerogative, and belongs wholly unto Thee. Though they persecute me unto death, and pant after the very dust upon the heads of Thy poor, though they have taken the bread out of Thy children's mouth, and have made me a desolation; yet, Lord, give me Thy grace, and such a measure of charity as may fully forgive them." It may have been during some such time of trouble, or imprisonment, if imprisonment there was, that Vaughan's wife lived with Thomas Vaughan, as will be seen below, in London. (d) THOMAS VAUGHAN. It has not been thought necessary to reprint in this edition of Henry Vaughan's poems the scanty English and Latin verses of his brother, Thomas Vaughan. They may be found, together with verses by Virgil and Campion ascribed to him, in vol. ii. of Dr. Grosart's _Fuller Worthies_ edition. But some account of so curious a person will not be out of place.
