he should have undertaken many controversies, which required many quotations and turned upon minute points of detailed knowledge. That he should have been able to do this was owing to his accurate memory, of which he says that he 'always thought that tenure in capite was a nobler and more honourable tenure than to hold by copy' (Extraneus Vapulans, p. 132).
Heylyn's most important books were finished during the last years of his life, and were intended to furnish a complete survey of the ecclesiastical questions of his time. They are valuable as an exposition of the historical views of the Laudian school, and show both the basis of sound knowledge and the one-sided application of it to current questions which mark Laud's policy. In Heylyn's works we find the literary justification of Laud's conduct, especially in 'Ecclesia Restaurata,' 'Cyprianus Anglicus,' and 'Aerius Redivivus.' 'Ecclesia Restaurata, or the History of the Reformation,' was published in London in 1661, and went rapidly through two other editions, 1670, 1674; the last edition has emendations, apparently by the author; it was edited in 1849 by the Rev. J. C. Robertson for the Ecclesiastical History Society. The history extends from the accession of Edward to the completion of the Elizabethan settlement in 1566. Heylyn has not brought to light any new facts, but he is the first writer who has attempted to estimate the losses as well as the gains of the religious convulsion of the sixteenth century. He dwells upon the irregularities and disorders as a justification of Laud's attempt to restore ecclesiastical order. 'Cyprianus Anglicus, or the History of the Life and Death of William Laud, Archbishop of Canterbury' (1668, 1671, 1719), is a defence of Laud against Prynne's 'Canterburies Doom,' and is the chief authority for Laud's personal character and private life. 'Aerius Redivivus, or the History of Presbyterianism' (1670, 1672), traces the origin of the English troubles to the spirit of the puritans, by showing that their party, from the days of Calvin, had been the source of civil discord. Besides these was published in 1681 'Kειμήλια ἐκκλησιαστικά, or Historical and Miscellaneous Tracts,' containing (1) 'Ecclesia Vindicata, or the Church of England justified,' originally published in 1657, which incorporated several other works, such as 'The History of Episcopacy' (1642), 'The History of Liturgies,' 'Parliament's Power in Laws for Religion' (1645), and 'The Undeceiving of the People in the Point of Tithes' (1648); (2) 'The History of the Sabbath,' 1635; (3) 'Historia Quinquarticularis, or a Historical Declaration on the Five Controverted Points reproached in the name of Arminianism,' originally published in 1660; (4) 'The Stumbling-block of Disobedience and Rebellion,' originally published in 1658; (5) 'De Jure Paritatis Episcoporum.' A full list of Heylyn's writings is in Wood's 'Athenæ,' iii. 557–67.
[There are two Lives of Heylyn by contemporaries, and it would seem that Heylyn's controversial spirit affected even his biographers. When the tracts were preparing for publication in 1681 the publisher applied to Heylyn's son for a biographical introduction. The commission was given to George Vernon, rector of Bourton-on-the-Water, Gloucestershire, but when the manuscript was delivered the publisher was disappointed to find that it was not from the pen of Heylyn's son-in-law, John Barnard or Bernard [q. v.] , rector of Waddington, Lincoln, who had been set aside owing to family differences. The publisher sent Vernon's manuscript to Barnard who made great alterations, which were submitted by the publisher to Thomas Barlow, bishop of Lincoln, who corrected unsparingly the result of the previous revision (Wood, Athenæ Oxon. iv. 606). This is the origin of the Life prefixed to the Tracts. Its appearance in this mutilated form excited the wrath of Vernon and Barnard alike, and in 1682 Vernon published his Life of Dr. Peter Heylyn, with a preface that seemed to reflect on Barnard. This provoked Barnard to publish in 1683 Theologo-Historicus, or the True Life of the most reverend Divine and excellent Historian, Peter Heylyn, D.D., with a long preface directed against Vernon (see Disraeli, Curiosities of Literature, ed. 1849, iii. 238). The statements contained in these competing biographies do not materially differ. Barnard's Life has been printed by Robertson in his edition of the Ecclesia Restaurata, incorporating from Vernon any additional information. See also Wood's Athenæ Oxon. iii. 552–569; Walker's Sufferings of the Clergy, ii. 90; Lloyd's Memoirs of the Lives of Excellent Personages who suffered for Protestantism, pp. 525–8.]
HEYLYN or HEYLIN, ROWLAND (1562?–1631), sheriff of London, was descended from an ancient family seated at Pentreheylin in the parish of Llandysilio, Mongomeryshire, whoae members were hereditary cupbearers (as the name signifies) to the princes of Powys. The names of Heylyn's parents are not known. According to the records of the Ironmongers' Company of London he was born in 1562. On 30 April 1575 he was apprenticed to Thomas Wade, was admitted to the freedom of the Ironmongers' Company on 4 May 1584, was an assistant in 1612, and served as master in 1614 and 1625. Heylyn lived in the parish of St. Alban,
