In The Center of the Circle: The Marvelous Lamp of Valle-Inclán, Professor Emerita of Spanish Virginia Milner Garlitz studies the work of Spanish dramatist and novelist Ramon del Valle-Inclán (1866–1936) and examines the revival of interest in the occult at the turn of the twentieth century in Europe, promulgated by such groups as the Theosophical Society and the Rosicrucians. Their idea of centering within the circle provided Valle-Inclán with the theme that guides the structure and the verbal and graphic imagery of his key aesthetic treatise, The Marvelous Lamp.

Garlitz’s book was published in 2007 by the Council of Valle-Inclán Studies at the University of Santiago, Compostela, where Valle-Inclán himself studied.
