He was succeeded by _Thadeus_, who was consecrated at Rome, in the Church of St. Mary _Supra Minervam_, on the 10th of September, 1469. His death is registered in the year 1486, and his successor, _Tiberius_, during along and eventful episcopate, governed this see till his death in 1519. Ware, indeed, supposed that his episcopate continued till _circa an._ 1526; but Reeves discovered an ancient record which describes the see as vacant by our bishop's death in 1519--(_Ec. Antiq._, page 160). The historians of the Augustinian order mention a Bishop Thadeus, who seems to have succeeded in 1520, and held the see till 1526. Robert Blyth, a Benedictine and abbot of the monastery of Thorney, in Cambridgeshire, received this diocese _in commendam_ by royal privilege in 1526. Dr. Cromer, Archbishop of Armagh, refused to give his sanction to this commendatory jurisdiction, and appointed to various benefices of Down and Connor, assigning as his motive the absence of the bishop, "in remotis agentis sine licentia summi Pontificis aut Metropolitani sui". Dr. Blyth, however, continued to administer the diocese till 1540, when he resigned this charge, and had for his successor Eugene Magennis, who was proclaimed in consistory Bishop of Down and Connor in 1541. This Bishop submitted his Bulls to the crown in 1542, and hence was admitted not only to the temporalities of the see, but received in addition other ecclesiastical benefices. On May 9th, 1543, a further writ of pardon was issued in his favour (see _Morrin_, i. 91); but in all these acts of submission no mention is made of the royal supremacy. The position of his see rendered his submission in temporals too important to the crown to introduce any such embittering clause, and, in fact, the northern chieftains who submitted at the same time were exempted from all reference to religion when professing their allegiance to the government. At all events, no doubt can be entertained of the orthodoxy of this prelate, and in addition to the proofs adduced by other writers, we may mention the consistorial record for the appointment of his successor, in which the see is described as vacant, not by the apostacy or deposition, but simply as is usual in regard of the Catholic bishops, _per obitum Eugenii Magnissae_.
