Pottwal
The whale industry on the Inishkeas did not begin and end at the beginning of the 20th century. Sperm whales were a common sight off the coast during the Middle Ages and the most important product at the time to come from the sperm whale was its vomit, Ambergris. Ambergris is highly valuable because it has a sweet scent and is sold as perfume and medicine. It was traded in the 17th century from the coast of Connacht through Galway to Spain and onto the spice markets of Cairo and Baghdad where he said it was worth a 'small fortune'.
