Pair of 18th C. Chinese Export Famille Rose Trembleuse Cup Stands

A pair of shell-shaped Chinese export porcelain trembleuses with molded bodies, circa 1770.
 
Dimensions: Each approximately 9” x 8½” x 2¾”
 
Decoration:  
The body is covered with a gold filigree pattern.
 
There is a floral cartouche at the foot of the shell-shaped body.
 
In addition, there are three leaf-shaped cartouches. The two to the right and left of the cupholder contain floral sprays. The larger one at the top contains images of women in various poses, trees, and a horse.
 
The orange pierced cup holder has a saw-tooth edge to give it the appearance of an opening flower.
 
The reverse is unmarked.
 
A trembleuse is drinking cup and saucer which originated in Paris in the 1690s. It was designed to allow people suffering from the trembles to drink a beverage without spilling. The cup sits in a saucer with either a well, or a raised rim to prevent the liquid from spilling.
 
While lore has it that this form was developed for the Viceroy of Mexico who suffered from Parkinsons, the form was already in use in Europe. However, Chinese export examples would have been exported to the Spanish market, including to its American colonies.
 
Condition: While both are in excellent visual condition consistent with age and usage, it appears that the fretwork of one trembleuse has been professionally restored.
