#Emer Foltchain (fairhair), daughter of Forgall Manach, was courted by #CuChulainn. She would only marry him if he first slew a hundred at the fords between the Delvin and the Boyne. Among them must be her magical aunt, who in various forms was trying to kill her. CuChulainn had to jump over all three walls of her fortress, Luglochta Logo, and behead eight men in a one fell swoop, before he could marry Emer. But Ulster's greatest hero was not allowed to harm her brothers.
CuChulainn had to rob Emer and her foster sisters from the castle and weigh her with gold and silver. He had to be able to go from #Samhain to #Imbolc and from #Beltene to #Lughnasa without sleep, otherwise Emer would not have married him.
Forgall Manach, Emer's father, tried to prevent their marriage but was unable to do anything due to CuChulainn's exploits. Source: Sylvia Botheroyd "Irland"
