Cathy FitzGerald invites you to discover new details in old masterpieces, using your phone, tablet or computer.

Each 30 minute episode of Moving Pictures is devoted to a single artwork - and you're invited to look as well as listen, by following a link to a high-resolution image made by Google Arts & Culture. Zoom in and you can see the pores of the canvas, the sweep of individual brushstrokes, the shimmer of pointillist dots.

We start this series with a masterpiece by Peter Paul Rubens, from the collection of the National Galleries of Scotland. Two metres high by nearly three metres wide, The Feast of Herod is painting on a grand-scale - its figures are almost life-size. The picture depicts an opulent banquet to mark the birthday of the ruler, Herod. His guests are adorned in sumptuous clothes and jewels; servants carry in elaborate dishes.

But beneath the surface of this fancy family dinner, something has gone terrifyingly wrong.
