Chinese Monastery Stamp or Seal Depicting Poem

Meet a big circle of coiled script sits inside a square block with decorative corners.

This monastery stamp or seal depicting a poem is from China, and dates to the early 20th century. It is soapstone. Chinese seals are carved in reverse so that the impression reads correctly, and the characters are often cut in an archaic script chosen for its look. The square face holds a circular field of curving characters, with small ornamental motifs filling the corners. The surface is a smoky, mottled grey with dark brown lines and a few spots of red in the carved recesses. It is 3 inches wide, 1.5 deep and 3 high.

Circles within squares, and everything running in loops.
