“Mermaids have long fascinated us. Humans have always wondered what it would be like to fly high above the clouds or dive deep into the briny seas. With nearly three-quarters of the Earth covered by water, its little wonder that centuries ago, the oceans were believed to contain many mysterious creatures, including sea serpents and mermaids.
Merfolk (mermaids and mermen) are of course only the marine version of the half-human, half-animal legends that have captured human imagination for ages. Greek mythology contains stories of the god Triton, the merman messenger of the sea. Some people around the world even worship mermaids as goddesses! In secular folklore, mermaids were often associated with bad luck and misfortune, luring errant sailors off course and even onto rocky shoals. In some legends from Scotland and Wales, however, mermaids befriended, and sometimes fell in love with humans.” —Reference: Mermaids & Mermen: Facts & Legends.
