Patrick was probably an Armoric Gaul born near Boulogne. As a youth he was captured and brought to Ireland, where he served Milchu. Having escaped and returned home, his subsequent mission back to Ireland is detailed in 288.13-289.24. When he landed in Ireland's Leinster for the second time he converted its natives to take off their Borsalino hats whenever they came within earshot of a Christian temple. He also taught them to pray and his cult still prevails mightily there in spite of all the religious blood since shed. The people believe in the institutions of the missionary of the Papal Propaganda, and it is believed that not all sorts of bribery with soup and not all kinds of gold would ever induce them to change back to their ancient worship of the thundergod. Patrick apostrophizes heilsermons which his descendants perpetuate. As we tropp along to church, talking of megalomania and missions against snakeworship (Patrick banished the snakes), of course this has blame all in that Mediterranean world to do with the judgements emanating from Peter's throne (hence the Paschal controversy).  

We now 'return for a moment from the reptile's age to the coxswain on the first landing.' The reptiles are not only Patrick's 'Creeping Crawleys' but also include the dragon slain by Tristan on his second Irish visit. The Tristan element is stressed from this point, although the date of Patrick's mission (432 AD) is supplied at 290.05. On Tristan's first landing he was dying from wounds received in his fight with the Irish champion Marhault, but Isolde cured him by the application of herbal preparations, 'a Blinkensope's cuddlebath at her proper mitts'.
