In the form in which Rochfort quotes it the ordinance applies to the whole of Ireland. But we have no evidence of the transformation of dioceses into deaneries outside Meath; and it is quite probable that a synod held in Meath would have in view, in such a decree, only the conditions which prevailed in that district. [31] The deanery of Dunshaughlin is now named Ratoath. The deanery of Kells has been divided into Upper and Lower Kells. [32] The cogency of this argument is enhanced when we observe that there is strong independent evidence for the existence in the twelfth century of one of the six dioceses--the diocese of Kells. (_a_) Up to the latter part of the sixteenth century (1583) there was an archdeacon of Kells, as well as an archdeacon of Meath; the jurisdiction of an archdeacon (at any rate in Ireland) seems to have been always originally co-extensive with a diocese. The first known archdeacon of Kells was Adam Petit who was in office in 1230 (_R.T.A._ 279; _C.M.A._ i. 101); but it is unlikely that he had no predecessors. (_b_) Among the prelates who greeted Henry II. at Dublin in 1171 was Thaddaeus, bishop of Kells (Benedict of Peterborough (R. S.), i. 26). (_c_) In the time of Innocent III. (1198-1216) the question was raised in the papal curia whether the bishop of Kells was subject to the archbishop of Armagh or the archbishop of Tuam (Theiner, p. 2). (_d_) The bishop of Kells is mentioned in a document of the year 1202 (_Cal. of Docts. Ireland_, i. 168). (_e_) A contemporary note records the suppression of the bishopric: "When a Cistercian monk ... had been elected and consecrated bishop of Kells by the common consent of the clergy and people, and had been confirmed by the Pope, the impudent bishop of Meath cast him out with violence and dared to [add] his bishopric to his own" (_C.M.A._ ii. 22). This statement implies that the dispossessed bishop ruled over a diocese. Moreover, when we remember that the see was certainly suppressed before Rochfort's Synod of 1216, that Rochfort was the first person who assumed the title "bishop of Meath" in the modern sense, and that a bishop of Kells died in 1211 (_A.L.C._), we need not hesitate to conclude that the "impudent bishop" was Rochfort himself, and that the suppression was accomplished about 1213.
