In ancient Roman mythology, Salacia (/səˈleɪʃə/ sə-LAY-shə, Latin: [saˈɫaːkia]) was the female divinity of the sea, worshipped as the goddess of salt water who presided over the depths of the ocean.

[6] The god Neptune wanted to marry Salacia, but she was in great awe of her distinguished suitor, and to preserve her virginity, with grace and celerity she managed to glide out of his sight, and hid from him in the Atlantic Ocean.

Salacia agreed to marry Neptune and the King of the Deep was so overjoyed at these good tidings that the dolphin was awarded a place in the heavens, where he now forms a well known constellation Delphinus.

[citation needed] Salacia is represented as a beautiful nymph, crowned with seaweed, either enthroned beside Neptune or driving with him in a pearl shell chariot drawn by dolphins, sea-horses (hippocamps) or other fabulous creatures of the deep, and attended by Tritons and Nereids.

[9] Derived from Latin sāl, meaning "salt",[10] the name Salācia denotes the wide, open sea,[11] and is sometimes literally translated as "the salty one".
