Dillus Farfog
A bearded man whose whiskers were needed by the warrior Culhwch to make a leash to hold the pups Aned and Aethlem during the hunting of the boar Twrch Trwyth.
According to the giant Ysbaddaden, who assigned Culhwch this task, the beard had to be plucked while Dillus was alive, and Dillus naturally would likely not take kindly to the procedure. Arthur’s warriors Cei and Bedwyr found Dillus in Pumlumon.
They waited for him to eat his fill of a pig and to go to sleep. When he was asleep, they struck the giant in the head, Cei dug a huge pit under Dillus’s feet where they trapped him. The two warriors plucked his beard with tweezers and then killed him. They brought the leash to Celli Wig (Celliwig) in Cornwall.
