reynslá

reynslá is a term originating from Old Norse, often translated as "rain-salve" or "rain-ointment." It refers to a traditional Icelandic practice of preparing and using a mixture believed to protect sheep from the harsh effects of rain and cold weather. This preparation typically involved rendering fat from sheep, often from the tail or flanks, and then mixing it with other natural ingredients.

The exact composition of reynslá varied by region and household, but common additions could include herbs, plant extracts, or even animal blood. The purpose was to create a barrier on the sheep's wool, repelling water and providing insulation against the elements. This was particularly important in Iceland's challenging climate, where prolonged periods of rain and cold could lead to hypothermia and disease among livestock.

Applying reynslá was a seasonal activity, usually undertaken before the onset of winter. The mixture would be smeared onto the sheep's fleece, offering a protective coating. While the practice is largely historical and has been superseded by modern veterinary medicine and husbandry techniques, it represents a significant aspect of traditional Icelandic agricultural practices and the deep understanding of animal care in a demanding environment. The knowledge of reynslá was passed down through generations, reflecting a practical and resourceful approach to animal husbandry.
