In the early nineteenth century, Australia remained largely uncharted, and doubt prevailed as to its unity as a continent. The 1801 expedition led by English mariner and cartographer Matthew Flinders (1774–1814), on board the Investigator, was groundbreaking in this respect. Flinders' charting of the Australian coastline provided the first complete map outlining the continent, and his influence was decisive in changing its name from Terra Australis to Australia - a term 'more agreeable to the ear'. Structured around daily geographical and astronomical observations, Flinders' journals are remarkable for their humanity and their sense of humour. Started in 1801, they continue to include Flinders' imprisonment by the French in the island of Mauritius between 1803 and 1810. They were first published in 1814, the day before Flinders' death. Volume 1 spans the first two years of the expedition and focuses on the discoveries made along the south coast of the continent.
