The Algea were the personifications of sorrow in Greek mythology, daughters of the goddess of strife, Eris. The Algea had numerous siblings, including Horcus, Ponos, Limos, the Hysminai, the Makhai, the Phonoi, the Androktasiai, the Neikea, the Pseudologoi, the Amphilogiai, Dysnomia, Ate, and Lethe. They were all personifications of wrong doings or negative situations, such as pain, fights, murder, lies and forgetfulness. They were related to Oizys, god of misery, and Penthos, god of mourning. Their opposites were the goddess of pleasure, Hedone, and the Charites, goddesses of joy.
There were three Algea; Lype, personification of pain, grief and distress; Ania, personification of distress, sorrow, and boredom; and Achus, personification of anguish.
