A Short time ago I took an opportunity of laying before the Society of Antiquaries by your hands, a Letter containing much interesting information on the state of parties in the year 1454; and I now beg leave to add, as a supplementary communication, copies of several Political Poems written at various periods of the reigns of Henry the Sixth and Edward the Fourth, all of which, with the exception of the first, have hitherto remained unpublished. Documents of this kind are confessedly not beneath the notice of the historian, since they shew the popular feelings of the time better than any other contemporary record, and often mention minute circumstances worthy of note, which may in vain be sought for elsewhere. In the Transactions of the Society some few specimens of this political versification have already appeared, of the reigns of Edward the Third, Richard the Second, and Edward the Fourth, and some others belonging to the reign of Henry the Sixth, may be found in the Excerpta Historica Of the six poems now sent, five were composed by adherents of the house of York, the first of which relates to the murder of the Duke of Suffolk, in 1450; the second to the chiefs of the Yorkist faction, probably about May, 1460; the third to the battle of Northampton, in July following; the fourth, to the policy and position of the adverse parties, probably towards the end of the same year; and the fifth to the battle of Towton, in 1461. The remaining poem was written by a Lancastrian, and presents a curious contrast to the others. It enumerates the principal Lords on the King's side, and, under the metaphor of a ship, describes the position of each in the guidance and government of the state towards the close of the year 1458.
