Shrinking the world in seven chapters - Sailing across the oceans - wind power.

This is the second in the series: ‘Shrinking the world in seven stages’. Imagine you have been asked to provide one or two creative and inspirational illustrations for a series of lectures. This is on sailing across the oceans and how wind power opened up transport around the world. Possibilities include: - a viking long ship. - a tea clipper. - a replica of a 15th century caravel. - the captain or crew of a square rigger or other historic wind-powered ship. - docks or dock buildings that pre-date the age of steam.
