In this artwork, how is the Description discussed?
The work is a triptych, although the scenes are set in the same location (an unusual feature for the time), a room whose vaults follow the shape of the panel; the scenes, painted using a crude geometrical perspective, are separated by two white piers in the foreground. The vaults have a starry night sky, as typical of Gothic edifices of the time.
The left scene depicts Joachim, Mary's father, waiting together with a child and an old man. Behind him, an opened lunette and arcade show the court of a Gothic palace. St. Anna is lying on a bed (a typical medieval chest) in the central scene with a white drape behind, while, in the foreground, two women are washing her daughter. A woman, wearing a red dress, is shown behind the right pier, while speaking with Anna; she holds an inlaid object,  perhaps a banner or a musical instrument. Two further women with washing accessories appear in the right panel.
