Niobid Painter (flourished c. 475–450 bce) was a painter of flower-shaped Greek vases who is named for a calyx krater (mixing bowl) with a representation of the death of the children of Niobe. The vessel is thought to reflect the innovative technique of the now lost mural paintings of Polygnotus, another Greek painter of the 5th century bce.
In the scene of the death of the children of Niobe and in the scene of Athena and Heracles on the other side of the krater, the Niobid Painter arranged his figures so that they are set on different levels, suggesting different ground lines by means of a fine painted white line. Landscape setting too is suggested: Athena and Heracles appear to be standing on a hilly terrain. Apparently, the Niobid Painter made a deliberate attempt to express space and depth.
