Le Temple de la Lumière (The Temple of Light)

Title from second drawing by this artist of the same subject (see 1986.2301).
One of a series of drawings to illustrate a French edition of Maurice Maeterlinck's The blue bird (i.e. L'Oiseau bleu); completed by Robertson in 1915, but evidently never published. Cf. Letters from Graham Robertson / edited by Kerrison Preston. London : Hamish Hamilton, 1953, p. 30-34.
