Here we have sufficient discrepancy to mark the independence of the writers, combined with a distinct agreement to the effect that Henry sent “nuncii” to Rome, that they took something with them to support the king’s petition, and that the Pope, in reply to it, sent something back. What was it? Here we must turn to a third quarter, where the evidence is wholly independent. This is the Black Book of the Exchequer in which are entered the three letters from Pope Alexander, all of them dated from Tusculum, 20th September, 1172. Miss Norgate, in her History, referred to them as documents of undoubted authenticity;[396] but in her article, though stoutly maintaining that their evidence was not hostile to the genuineness of the “Bull,” she seems to have felt uneasy on the subject, for she changes her tone, and writes that they “purport to have been written by Pope Alexander III.,”[397] nay, even speaks of them as Alexander’s letters, “if they indeed are his.”[398] To these letters, which Cardinal Moran pronounced “certainly authentic,” I now invite attention. The first, which is addressed to Christian bishop of Lismore (the legate), the four archbishops (by name), and their suffragans the bishops, speaks of the “vitiorum enormitates” made known to the writer by their letters (“ex vestrarum serie literarum,” “ex vestris literis”) and the “abominationis spurcitiam.”[399] No more exact agreement could be found than this document presents with the statement of Giraldus that the Legate’s letters, on behalf of the assembled prelates, recited “tam enormitates quam spurcitias” of the Irish. Again, the third letter, “to the kings and princes of Ireland,” similarly charges the Irish with “enormitatem et spurcitiam vitiorum”; and it confirms not only Giraldus but the ‘Gesta’ by its words: “in vestrum Regem et dominum suscepistis et ei fidelitatem jurastis ... vos voluntate libera subdidistis ... fidelitatem quam tanto Regi sub juramenti religione fecistis.” Their “juramenti debitum et fidelitatem predicto Regi exhibitam” is spoken of also in the letter to the prelates. Passing now to the second letter, which is to Henry himself, it introduces a new element; for while that to the prelates had referred to their letters and “aliorum etiam veridica relatione,” a vague phrase which, in the letter to the princes, reappears as “communi fama et certa relatione,” the Pope, in writing to the king, gives as his sources of information, first, the letters from the Legate and Prelates, and then the _viva voce_ statements of Ralf archdeacon of Llandaff.[400] Now we know from the ‘Gesta’ that this Ralf was sent by Henry to hold the Council of the Irish Prelates at Cashel;[401] and we further know that the king had sent him to Rome as an envoy in the Becket business some two years before.[402] We have then, in this letter, confirmation of the fact that Henry sent a mission, with the prelates’ letter, to Rome, while
