Lúin of Celtchar
In the Ulster Cycle of early Irish literature, the Lúin of Celtchar (Irish: Lúin Celtchair) is the name of a long, fiery lance or spear belonging to Celtchar mac Uthechar and wielded by other heroes, such as Dubthach, Mac Cécht and Fedlimid. == Properties == Detailed descriptions of the spear's special use and terrible effect are to be found in the Middle Irish texts Togail Bruidne Dá Derga ("The Destruction of the Hostel of Da Derga") (Recension II) and Mesca Ulad ("The Intoxication of the Ulstermen"), both of which employ the so-called "watchman device" to describe the fearful appearance of the warrior Dubthach Dóeltenga.
