It is probable that the Book _of the Seedis of Profetis_, and the Book _of the Deedis of Profetis_, may be the same; the Word _Deedis_ or _Seedis_ being one or other of them a Mistake of the Transcriber. If the Word _Seedis_ be correct, the Title of the Work was probably _De seminibus prophetarum_; unless we take _Seedis_, as derived from the Verb _to say_, for _dicta_; for which there seems no Authority, especially as we find _Seyingis_ used to express _dicta_, in the very Passage before us. From the other Reading, the Title of the Book would be _De gestis prophetarum_. The Book _Of the Seyingis of Popes_ may, perhaps, be meant for the _Liber de Flore_ of the Abbot _Joachim_, which the Author of his Life[52] tells us was also called _De summis pontificibus_. It is quite obvious, however, that if these Books contained the Doctrine for which they are quoted by _Wycliffe_, (viz. that the Year 1400 was to be the Date of the Revelation of _Antichrist_,) they could not have been genuine Productions of the Abbot _Joachim_. The Opinion of _Joachim_ was, that the Year 1256 would be the Era of the total Extinction of the Christian Church, and that the Triumph of _Antichrist_ was then to commence, and to continue for three Years and a half, counting from the Middle of the Year 1256, to the End of the year 1260. As in the Lines:— _Hoc ~Cistercienni Joachim~ prædixit in anno_ _Quo ~Saladinus~ sanctum sibi subdidit Urbem,_ _Cum fuerint anni completi mille ducenti,_ _Et seni decies a partu ~Virginis~ almæ,_ _Tunc ~Antichristus~ nascetur demone plenus._[53]
