One of the great losses of the pandemic for the art world has been unexpected closures of numerous exhibitions worldwide. Perhaps the most missed, because it entailed such a monumental task to bring works together that had last been partially brought together in the early 19th century, was Van Eyck. An Optical Revolution. What a loss and what a joy for those few who saw it before it closed, Van Eyck’s brilliance refreshes the soul. Fortunately its available online and well worth viewing.
