Heavenly messenger with an announcement for a seated man in a palace

A figure dressed in red and white with a halo of flames around the head stands before a seated figure in a room in a palace; the seated figure holds the left hand of the standing messenger and looks up at him; the messenger has his right hand slightly raised in a giving gesture; in the foreground, a terrace with a pond is visible, and in the background, a rocky garden with a tree. The composition is framed by a few colored border lines and mounted on a larger golden-speckled sheet.
