Optical principles are straightforward, but can become extremely complex in practice. Examples from Jan van Eyck to Hodler and Signac.
Signac
After a promisingly Realist start at the age of just 17, he progressed through Impressionist style and became a Divisionist in 1887-88.
Milliners trimmed and sold hats to customers, which appeared to be more rewarding, and the chance to wear the latest fashions.
From Quiberon and the Vendée to Hendaye and Hondarribia, in paintings from Renoir, Signac, Pierre Bonnard and others.
From the rough seas and rugged cliffs of Penmarc’h to Belle-Île, with Monet, Signac, Berthe Morisot and other artists.
Shipwreck in The Tempest, forgotten Impressionists, a threshing machine, a weekend on the River Seine, a pair of portraits of Thomas and Susan Eakins, a pair of clowns, and more.
Don Quixote, Netherlandish Proverbs, grain fields in Ukraine, a flock of sheep in a boat, the Golden Horn, pastels and kabkabs.
Paul Signac, Paul Nash, Pierre Bonnard, Lovis Corinth and others, even a painting by Paul Klee, for an eclectic collection.
Reflections seen in landscapes from Dürer’s pioneering watercolour, through Poussin and Turner to Monet, Sisley and Neo-Impressionists.
From Rubens’ double-portrait with Isabella Brant, and Rembrandt’s with Saskia, to Paul Signac’s wife with a parasol and Ferdinand Hodler’s wife Berthe Jacques.
