LONDON.- The first major canvas by Mark Rothko to be presented in a London auction in a decade, the spectacular Untitled was executed in 1955 (estimate on request). Realized at the height of the artist’s celebrated classic period, it forms part of a series of abstract works exhibited and owned by a number of major international museums. Rendered in a palette of brilliant red vermillion, burnt ochre and white, Untitled comprises two rectangular forms floating within the canvas. Faced with this large-scale and vivid piece, ‘abstract sublime’ and ‘spiritual awe’ are amongst the terms used to describe this work which inevitably provokes a wealth of emotions for the transcended viewer.
