This model of vase is made in two parts. The flared upper section would have contained earth for growing plants; the lower section held water. Small holes in the base of the upper section allowed the water to be absorbed. These two vases formed a garniture with the slightly earlier vase, "vase Boileau" (50.211.158a, b), and were owned by Prince Henry of Prussia.
