Each Hero in Irish Mythology had his favourite sword, and some of these achieved legendary status.
One of the most legendary objects in Irish Mythology was the Gae Bolga, granted to Cuchulainn by Scathach. This was a spear, which separated into many barbs on entering the body. It was impossible to remove, and its wound was fatal. Only one of these existed, and it was the preserve of Cuchulainn, thus further underlining his status as the champion of all Ireland.
Diarmuid had two swords depending on the type of fighting necessary; Moralltach – Great fury – and Beagalltach – Small Fury. It was with Moralltach that he slew the giant guarding the tree of the berries of youth, and it was because he left his sword at home on the day of his final hunt that he was unable to defend himself against the magical boar that attacked him.
The God Manannan owned a boat named the Wave Sweeper, which could grow to accommodate any number of passengers and did not require oars or sails in order to move.
Irish folktales are full of objects such as magic shoes for swift walking, magic cloaks of invisibility, magic keys to open any locks, and magic sticks that grew to form bridges or supports. Once these objects were used they generally disappeared and returned to the fairy world from which they usually came.
From the fairy world also came the Banshee – which literally means a woman of the fairies. It was said that the Banshee would only walk near the house of one who was about to die.
