50 Works of Art to See Before You Die.

So - what are the journeys that are really worth making to see art? To launch the Guardian's new arts blog, let's work together to make a definitive list of works of art everyone should, at least once in a lifetime, travel to encounter - a list of 50 Works of Art to See Before You Die.

I'm kicking off the debate by listing my own top 20 (see a slideshow of the works here):

Jan van Eyck, The Madonna of Chancellor Rolin, c.1435, Musée du Louvre, Paris

Caravaggio, The Burial of St. Lucy (1608), Museo di Palazzo Bellomo, Syracuse, Sicily

Rembrandt, Aristotle with a Bust of Homer (1654), Metropolitan Museum of Art, New York

San Rock Art, South African National Museum, Cape Town

Paul Cézanne, Mont Sainte-Victoire from Les Lauves (1904 - 6), Pushkin Museum of Fine Arts, Moscow

Michelangelo, Moses (installed 1545), Church of San Pietro in Vincoli, Rome

Leonardo da Vinci, The Adoration of the Magi, (c. 1481), Uffizi Gallery, Florence

Mark Rothko, The Rothko Chapel (paintings 1965-66; chapel opened 1971), Houston, Texas

Vermeer, View of Delft (c.1660-61), Mauritshuis, The Hague

Matthias Grünewald, The Isenheim Altarpiece (c.1509-15), Musée Unterlinden, Colmar, France

Hans Holbein, The Dead Christ, (1521-2), Kunstmuseum, Basel

Velázquez, Las Meninas (1656), Museo Nacional del Prado, Madrid

Funerary Mask of Tutankhamun (1333-1323BC), Egyptian Museum, Cairo

Jackson Pollock, One: Number 31, 1950, Museum of Modern Art, New York

Masaccio, The Expulsion of Adam and Eve from Paradise (c.1427), Brancacci Chapel, Santa Maria del Carmine, Florence.

Pablo Picasso, Guernica (1937), Reina Sofia Museum, Madrid

Titian, Danaë (c. 1544-6), Museo Nazionale di Capodimonte, Naples

Raphael, The School of Athens (1510-11), Stanza della Signatura, Vatican Palace, Rome

Parthenon Sculptures ("Elgin Marbles"), c. 444 BC, British Museum, London

Henri Matisse, The Dance (1910), Hermitage Museum, St. Petersburg, Russia

These are the works I swear by, always return to, and cannot forget. They are masterpieces that I guarantee will enrich, even change, your life. But my point of view is partial. It is Eurocentric for one thing - I expect the Guardian's millions of readers around the world to help correct that. On the other hand, I will be fighting my case. I think a work of art worth travelling to see has to be a really great statement about serious things. Something not just to fill your life but deepen it. What do you think? What do you love? Have your say and help complete this list of the supreme art of all time.
