Art historian Lourdes Cirlot explained in a vibrant conference a tour through the work of Bill Viola, with projected images that allowed the public of Saint Cecilia Chapel get immerse themselves in the work of one of the most committed artists in spirituality. Cirlot insisted in how the artist works on the theme of life and death along its path of video-creations. This cycle has always been there and treated in the work of Viola from different perspectives: Christianity, Zen, Buddhism and others. The result is a stunning work that has its precedent in the tradition but develops technologically in the most present way.
