mitaarfik (11. 248)

Via Strange Company just in time for Three Kings Day (Kunngit Pingasut Ulluat), the apparitions usually first appearing on the Eve of Epiphany and continuing through the holiday marking the end of Christmastide, we are introduced to the terrifying figure of the Mitaartut a silent, masked mummer that sneaks up on people in the dark Greenlandic night. As with other syncretic traditions like that of Krampus and related rites, the coming of the Mitaarfik mixes indigenous customs and trappings like the harpoon and seal-skins with Christian ceremony and is adaptable to contemporary interpretation.
