Editing Manannán mac Lir (section)

=== County Monaghan ===
There are many oral folktales about conflicts between Manannán and St. Patrick in County Monaghan. In many of them Manannán invites St. Patrick to his castle for a feast; however, Patrick is warned by a butler or servant not to eat the food because it is poisoned. In retaliation for the crime, Patrick turns Manannán into a giant eel or salmon,<ref>{{Cite web |title=St Peter's, Phibsboro {{!}} The Schools' Collection|url= https://www.duchas.ie/en/cbes/4428244/4388010|access-date=25 December 2021|website=dúchas.ie}}</ref> and in some stories he is placed in a bottle and sent to the bottom of a lake to guard his iron treasure chest (or barrel) until the end of time.<ref>{{Cite web |title=Manann Castle |url= https://www.duchas.ie/en/cbes/4723817/4716065/4743504 |access-date=25 December 2021 |website=dúchas.ie}}</ref><ref name="Manann Castle">{{Cite web |title=Manann Castle |url= https://www.duchas.ie/en/cbes/4758587/4756881/4936445 |access-date=25 December 2021 |website=dúchas.ie}}</ref> The treasure is chained to a team of white horses, and the chain can be seen at the top of the lake.<ref>{{Cite web |title=Caisleán Mannan |url= https://www.duchas.ie/en/cbes/4742041/4730189/4950954 |access-date=25 December 2021 |website=dúchas.ie}}</ref> In one story from County Monaghan, Manannán's castle was built with mortar from the blood of slaughtered animals, which allowed it to resist weathering for centuries.<ref>{{Cite web |title=St Peter's, Phibsboro {{!}} The Schools' Collection|url= https://www.duchas.ie/en/cbes/4428244/4388009|access-date=25 December 2021|website=dúchas.ie}}</ref> When the top of the castle toppled over, the bottom part sank into the ground, but the ruins could still be seen owing to the power of Manannán. In some stories, Manann was said to ride a flying white steed and could transform himself into a dove and could be heard crying every seven years.<ref name="Manann Castle" />

In another story, Manann was a druid who challenged St. Patrick over whose god was more powerful. Manann covered the land in darkness, but St. Patrick placed his crozier in the ground, prayed to God, and dispelled the darkness. At the spot where St. Patrick placed his crozier, a well called ''Tobar Lasar'' sprang from the ground.<ref>{{Cite web |title=Taplach {{!}} The Schools' Collection|url= https://www.duchas.ie/en/cbes/4758587/4756934/4936540|access-date=25 December 2021|website=dúchas.ie}}</ref>

In another story, villagers searching for Manann's treasure attempt to drain his lake, but just before they complete their task, a man on a white steed appears before them to send them on an errand. When they return a large rock is placed in the spot where they were digging, and no chisel or hammer can break it.<ref>{{Cite web |title=Composition - Hidden Treasure |url= https://www.duchas.ie/en/cbes/5162735/5159791/5163887 |access-date=25 December 2021 |website=dúchas.ie}}</ref> In a variant of this story, all the men's horses are killed, and the work they had completed to dig the channel was filled with silt.<ref>{{Cite web |title=St Peter's, Phibsboro {{!}} The Schools' Collection|url= https://www.duchas.ie/en/cbes/4428244/4388011/4510330|access-date=25 December 2021|website=dúchas.ie}}</ref>

In another story, Manann was said to live in a castle and own a fabulous cow and calf that gave milk to everyone in the parish who wanted it. Some of the older people were jealous of the cow's abundance, and an old Protestant woman went to milk the cow into a sieve. When the cow saw what has happening, it was enraged and she and her calf ran to Dunany Point in County Louth, where they were turned to stone.<ref>{{Cite web |title=Inniskeen {{!}} The Schools' Collection|url= https://www.duchas.ie/en/cbes/4758588/4757093|access-date=25 December 2021|website=dúchas.ie}}</ref>
