When Signac was thirty years old he travelled to Venice in Italy, where he saw Byzantine mosaics.

Mosaics are made from small stones, glass or other materials in different colours to create a whole picture.

Signac liked these mosaics so much that it changed the way he painted.

He started to use bigger, broader brush strokes.

Look closely to discover:

• The colours used to paint the rainbow, are they different to what you would use?
• The big, broad brush strokes on the buildings
• How do the gondoliers move the boats along?
