ORIGINAL AUTHORITIES.-Henry's laws are printed in W. Stubbs's Select Charters (Oxford, 1895) . The chief chroniclers of his reign are William of Newburgh, Ralph de Diceto, the so-called Benedict of Peterborough, Roger of Hoveden, Robert de Torigni (or de Monte) , Jordan Fantosme, Giraldus Cambrensis, Gervase of Canterbury ; all printed in the Rolls Series. The biographies and letters contained in the 7 vols. of Materials for the History of Thomas Becket (ed. J. C. Robertson, Rolls Series, 1875-85) are valuable for the early and middle part of the reign. For Irish affairs the Song of Dermot (ed. Orpen, Oxford, 1892), for the rebellions of the princes the metrical Histoire de Guillaume le Marechal (ed. Paul Meyer, 3 vols., Paris, 1891, etc.) are of importance. Henry's legal and administrative reforms are illustrated by the Tractatus de legibus attributed to Ranulph Glanville, his chief justiciar (ed. G. Phillips, Berlin, 1828) ; by the Dialogus de scaccario of Richard fitz Nigel (Oxford, 1902) ; the Pipe Rolls, printed by J. Hunter for the Record Commission (1844) and by the Pipe-Roll Society (1884, etc.) supply valuable details. The works of John of Salisbury (ed. Giles, 1848), Peter of Blois (ed. Migne), Walter Map (Camden Society, 1841, 1850) and the letters of Gilbert Foliot (ed. J. A. Giles, 1845) are useful for the social and Church history of the reign.
