Antique Chinese fan painting of a dramatic group of various rock formations. The painting is modeled after a painting by Jin Nong (1687–1773) from his Fruits & Flora series. The writing on the upper left hand side of the fan is a poem:

弁山有葉氏大小玲瓏石，
雙井黃家有爛溪，
溪々中石皆爲艺林所重。
余漫意寫之，
落々然如挹高人面目也。

Which translates as: On Bianshan Mountain are Ye's linglongshi rocks, large and small; and to the Huangs of Shuangjing there is Lanxi Stream, and all the rocks in the streams...

Bianshan is the name of a mountain in Huzhou. Ye seems to refer to the Song-dynasty poet Ye Mengde, who liked to collect special rocks from there. Examples of specific types of rock from Bianshan are Kunshi and Taihu rocks.
Shuangjing is the name of a village, and Huang here seems to refer to the Song-dynasty poet/painter Huang Tingjian.

There are a couple names that appear at the end: 訒厂 Ren'an, an artist name linked to Ye Fangai (葉方靄, 1629–1682). And 冬心先生 Dongxin Xiansheng, an artist name linked to Jin Nong ( 金农, 1687–1763). This name means something like "Mr. Winter Heart" or "Winter Heart Old Fellow". Also written is "after Dongxin Xiansheng".

The seal is the Chinese surname: 范: Fàn, possible by artist Fan Ren'an born 1916.

Dimensions: Fan: 9 1/2" high x 20 1/8" wide. Mounted on silk: 14 1/4" high x 23 3/8" wide.
