Thaleia was mentioned as one of the 33 Nereids who gather on the coast ofTroy from the depths of the sea to mourn withThetis who cried out in sympathy for the grief of her sonAchilles for his slain loverPatroclus inHomer'sIliad.[3]
In some accounts, Thalia, together with her sistersCymodoce,Nesaea andSpio, was one of the nymphs in the train ofCyrene[4] Later on, these four together with their other sisters Thetis,Melite andPanopea, were able to help the heroAeneas and his crew during a storm.[5]
