Mary, Seat of Wisdom (also known as Our Lady of the Chair or the Latin name Sedes Sapientiae), is a very old title for Mary. As with all of Mary’s titles, it highlights one specific aspect of her life and experience – specifically, her role as the one who gave birth to Christ.
Artistic representations of Mary, Seat of Wisdom often show her seated on a throne, holding the Christ child on her lap and offering him for adoration. Many early Christians saw Christ as Wisdom incarnate; therefore, by holding him on her lap, Mary becomes the “seat” of wisdom. On another, deeper level, the title also refers to the fact that Mary “held” wisdom inside her by carrying Christ in her womb.
