In some areas, mumming and guising were part of Samhain. It was first recorded in 16th century Scotland[89] and later in parts of Ireland, Mann, and Wales.[90] People went from house to house in costume or disguise, usually reciting songs or verses in exchange for food.[90] It may have evolved from a tradition whereby people impersonated the aos sí, or the souls of the dead, and received offerings on their behalf.[90] Impersonating these spirits or souls was also believed to protect oneself from them.[91] S. V. Peddle suggests the guisers "personify the old spirits of the winter, who demanded reward in exchange for good fortune".[92] McNeill suggests that the ancient festival included people in masks or costumes representing these spirits and that the modern custom came from this.[93] In Ireland, costumes were sometimes worn by those who went about before nightfall collecting for a Samhain feast.[90]
