The Pseudologoi were the personifications of lies in Greek mythology, sons of the goddess of strife Eris. They had numerous siblings, including Horcus, Ponos, Algea, the Hysminai, the Makhai, the Phonoi, the Androktasiai, the Neikea, Limos, the Amphilogiai, Dysnomia, Ate, and Lethe. They were all personifications of wrong doings or negative situations, such as pain, fights, murder, lies and forgetfulness.
According to a different source, however, there was only one Pseudologos, a female deity, created by Dolos, spirit of deception and apprentice of the Titan god Prometheus. Prometheus decided to create Aletheia, goddess of Truth, so that the decisions of humankind would be regulated by her. While creating her, Prometheus was called away by Zeus, leaving Dolos alone in the workshop. Dolos started using the remaining clay for a second sculpture, identical to the first, but he soon ran out of clay without finishing the feet of his sculpture. When Prometheus returned, he was awed by the similarity between the two sculptures and put both in the kiln. He then breathed life into them and two figures were created; the first, Aletheia walked carefully and in a measured way; while the second, Pseudologos (falsehood) lay still, as she had no feet.
