Editing Manannán mac Lir (section)

=== Merchant Orbsen ===
The 9th century {{lang|sga|[[Sanas Cormaic]]}} ('Cormac's Glossary') [[Euhemerism|euhemerizes]] Manannán as "a famous merchant" of the Isle of Man and the best sailor in western Europe, who knew by "studying the heavens" when the weather would be good and bad.<ref name="odonovan-cormacs-gl" /> O'Donovan's annotation remarks that this merchant went by another name, Orbsen, son of Allot,<ref name="odonovan-cormacs-gl" /> and it is stated thus in [[Roderick O'Flaherty]]'s ''Ogygia'' (1685).<ref name="oflaherty-ogygia-eng" />

However, the ''[[Yellow Book of Lecan]]'' (written c.&nbsp;1400) separates these figures, stating there were four individuals called ''Manandán'' who lived at different times. They were: ''Manandán mac Alloit'', a "druid of the Tuath Dé Danann" whose "proper name was Oirbsen"; ''Manandán mac Lir'', a great sailor, merchant and druid; ''Manandán mac Cirp'', king of the Isles and Mann; and ''Manandán mac Atgnai'', who took in the [[Deirdre|sons of Uisnech]] and sailed to Ireland to avenge their deaths.<ref name="Skene">[[William F.

Tradition has it that Orbsen engaged in the Battle of [[Moycullen]] in Co. Galway, and fell on the brink of Lake Orbsen;{{sfnp|O'Flaherty|1793|pp=26–27}} the lake, named after him, is the present-day [[Lough Corrib]].<ref name="odonovan-cormacs-gl" /> The conflict in which Manannan mac Alloid was slain by Ullinn was recorded in verse by 11th century poet [[Flann Mainistrech]].{{sfnp|O'Flaherty|1793|pp=26–27}} There is a great stone pillar erected in the field of Moycullin, possibly marking the battle location.{{Refn|group-lower-alpha|Borlase makes Orbsen and Ullinn who fought here as "two giants", but that was not stated by his source, O'Donovan.}}<ref>{{harvp|Borlase|1897|p=795}} and note ††, citing O'Donovan, O.S.L.

Oirbsen is also mentioned in the Lebor Gabala Erenn, where it gives his genealogy as follows: Galia s. Oirbsen s. Elloth s. Elada s. Delbaeth s.

It goes on to state: "Orbsen was the name of Manannan at first, and from him is named Loch Orbsen in Connachta. When Manannan was being buried, it is then the lake burst over the land, [through the burial]."<ref name=":0" />
