The chronological indications contained in VG are sufficiently close to accuracy to show that they have been calculated, though the computor has made a miscount of a year. The eighth of the calends of February (25th January) in A.D. 548 was actually a Saturday, but it was two days before new moon. The same day in A.D. 549 was the tenth day of the moon, but it fell on a Monday. Of the companions of Ciaran, Oengus (properly Oenna) succeeded him as abbot, dying in A.D. 569; Mac Nisse, who was an Ultonian, followed him, and died 13 June 584 (aliter 587). The others, however, do not appear to have found a place in the martyrologies. Mo-Beoc is a different person from the famous Mo-Beog of Loch Derg in Co. Donegal. XLII. THE FOUNDATION OF THE CHURCH (LA, VG) The two versions are independent. But though there are no wizards or druids in the VG version, they appear in another story connecting Diarmait with the foundation of Clonmacnois. This is to the effect that Diarmait was at a place on the Shannon near Clonmacnois, called Snam da En, and saw the glow of the first camp-fire lighted on the site of the future monastery by Ciaran and his followers. The druids who were with Diarmait told him that unless that fire were forthwith quenched, it would never be put out. "It shall be quenched immediately," said Diarmait; so with hostile purpose he advanced on Clonmacnois, but instead of doing what he proposed, he suffered himself to be pressed into the service of the builders, as the story in VG narrates. The tale in LA is interesting, as showing (1) the existence of a calendar of seasons lucky and unlucky for various enterprises, and (2) a spirit of kindly tolerance on the part of the pagan wizard. The wiles of wizards were exposed by various saints, _e.g._ by Aed and by Cainnech. These tales are curious; the wizard in each case appeared to pass through a tree, but the saint opened the eyes of the spectators, so that they saw him actually passing round it (CS, 353, 368; VSH, i, 156). This reads like the exposure of hypnotically induced hallucinations.[24]
