In Greek mythology, Amatheia (Ancient Greek: Ἀμάθεια means 'rears, nurses' or 'she is sparkling water'[1]) was the "fair-tressed" Nereid[2] and was described to have "azure locks luxuriant" or as some translations put it "long, heavy hair". As one of these 50 sea-nymphs, she was the daughter of the 'Old Man of the Sea' Nereus and the Oceanid Doris. Variations of her names were Æmathia,[3] Amathea[4] and Amathia[5] which means "queen of voice".
Amatheia and her other sisters appeared to Thetis when she cries out in sympathy for the grief of Achilles for his slain friend Patroclus.[6]
