Around 900, Vikings and Norse peoples utilized moss and wool in their cleansing practices, adapting to the harsh climates of Northern Europe. This resourcefulness highlights the ingenuity of these cultures in utilizing available materials for hygiene and warmth. The use of natural resources reflects the broader Viking ethos of sustainability and adaptation, which was crucial for their survival and success in various environments.

The Viking use of moss and wool around 900 AD is echoed in saga literature, where daily life is depicted alongside heroic deeds. Poets like Snorri Sturluson captured the practical aspects of Viking culture, enriching the narrative depth of their works and preserving the legacy of their people.
