See also: Lagos

Lagos (Greek: Λαγός) was the father, or the supposed father, of Ptolémée {{Ier}} Sôter, the founder of the dynasty of Lagides (the name of the dynasty is drawn from its patronym besides).

but it is possible that it is a posterior myth manufactured by Pausanias, to improve the image of the Dynastie of Ptolémées. Lagos seems to have been married later in Antigone, the niece of Antipater, with which he became the father of Bérénice, which was the fourth wife of its half-brother Ptolémée.
