According to Stephen Walsh's biography of Stravinsky (pp. 173-74), , the composer, in July 1912, visited Princess Maria Tenisheva's Arts and Crafts community at Talashkino. Roerich was already there, working on the interior decoration of a church on the estate.
The estate included

a workshop for the design and manufacture of folk-art reproductions and a museum for the princess's growing collection of genuine peasant artifacts. Roerich was an old friend of hers, and his work and enthusiasms embodied many of the different aspects of the Talashkino enterprise: painter and ethnographer, archaeologist and mythologist, he summed up that curious mixture of practicality and mysticism, of functional design and high art, of sociology and religion, which motivated so many Arts and Crafts communities at the time.

Stravinsky recalled that Princess Tenisheva put him up in a guest house ... Within a few days they had worked out a scenario and the movement titles, and Roerich had sketched his neo-primitve backcloths and costumes based on actual peasant garments owned by the Princess.
I did not know that there was a Roerich Museum on West 107th Street in New York City. Their website reproduces sketches for Massine's production, dated 1944. If you click "Decor and Costumes" on the menu, you'll be led to a series of Roerich's works in this field. Scroll down to find the way The Sage looked in 1944:
