"Mapmakers of Europe and navigators of the Indies once thought Australian seas washed the isles of gold. Even after navigators had seen the north-west coast of Australia it was named on one map the coast of gold. Unknown coasts were treasurelands; imagination shaped and gilded them. Then slowly Dutch and British voyagers tarnished the gilt, and Australia turned from a land of reward to a land of punishment when Great Britain dumped convicts and guards at Sydney in 1788. The imagination of the ancients had more truth than the knowledge of the moderns, but for two generations the settlers did not know that their prison had bars of gold."
