148 Proceedings of the Royal Irish Academy. 



These lists prove that the material of H passed through one and the same 

 hand before it issued in Z, B, and F. Since Z is a Middle- Irish redaction 

 of an eighth-century document, and since the conclusion of F is taken 

 dii-ect from Z, there can be no reasonable doubt that Flann of Monaster- 

 boice, reputed author of synchronisms and inscribed author of F, was also 

 the Middle-Irish redactor (and part-corruptor) of Z. It is also highly 

 probable that, having failetl by int«rpolations, omissions, and alterations, 

 to make Z conformable to the views of his school, Flann set to work 

 afresh and produce*^! B, using the Eusebian material which he foimd in Z 

 as his warp, but wea^^ng into it the Irish names and chronology accepted 

 by his o»ii school. The origin of some of the misspellings in Z, B, and 

 F can be traced to misreadings of archaic Irish writing. In compaiing 

 these lists, due allowance must be made for the freedom or negligence of 

 transcription after the lime of Flann. 



I have to thank Professor Kimo Meyer for a number of con-ections and 

 suggestions.
