Here's a breakdown:
* Origins: Icelandic horses are descended from horses brought to Iceland by Viking settlers around the 9th century.
* Unique Breed: Over time, they evolved into a distinct breed, isolated from other horse populations due to Iceland's geographical location.
* No New Discoveries: There wasn't a specific point in history where they were "discovered". They have always been there.
So, while we might talk about the history of the breed's development, there's no specific "discovery" date.
