(probably Loch Lurgan or Galway Bay) on Tir Find and Loch Cera or Findloch over the borders of Irrus. Interestingly enough, several major lakes and outlets, such as Lough Corrib, Lough Derg (Shannon), Shannon Estuary and Killary Harbour are not mentioned in any known myth. This may imply that at least some lake-bursts mentioned have been wrongly identified with smaller lakes, where, in fact, they may have been referring to one of the major lakes. The cave of St Patrick's Purgatory on Station Island in Lough Derg (Ulster), moreover, was identified in the Tractatus de Purgatorio Sancti Patricii as the entrance to the Underworld. The plains that supposedly had been drowned, had special names, which have been preserved in a 16th-century manuscript.
