Japanese 6-panel screen of geese and egrets

Pair of 6-panel screens; ink, colors, gofun (crushed calcified crustacean shell) and gold on paper framed by a double silk brocade border.
The screen on the right represents numerous geese (14), some flying down in front of a black moon, others in search of food or resting among the grass at the edge of a body of water with a background of a mountain.

The left screen depicts egrets (7), three of which are perched on the trunk of a majestic weeping willow, covered in a white pigment representing snow, one in flight downward and the others hunting in a stream.

The theme of these screens is the end of autumn and the arrival of winter.
The softness and tranquility of these seasons are particularly well represented by the pastel tones on all the panels.

Works of two pairs of geese among reeds and egrets with willows have existed in Japanese art since the Muromachi period (1336-1573). They were executed by famous artists such as Sesson Shokei (1504-1589) and Kan? Masanobu (1434-1530).

Each screen bears seals attributed to Kanô Sansetsu (1589-1651) but are not authenticated. The artist having undoubtedly left the authorship of these seals to a relative.
