My attention has been drawn to an interesting new article on the relationship with Traditionalism of the French Cubist painter Albert Gleizes (1881-1953). Witten by the painter and scholar Peter Brooke, it is entitled "Albert Gleizes, Coomaraswamy and 'Tradition,'" and is available here.
Brooke starts with a general discussion of Gleizes and Traditionalism, including the split in Gleizes' following between pro- and anti-Traditionalist factions that resulted in two rival artistic journals, L'Atelier de la rose (Traditionalist) and Zodiaque (Catholic). He then asks (a) what Guénon saw in Gleizes, (b) what Coomaraswamy saw in Gleizes, and (c) what Gleizes saw in Guénon and Coomaraswamy.
My thanks to SJ for drawing my attention to this article.
