Plate 52 from 'Journal de la navigation autour du globe de la fregate la Thetis et de la corvette l'Esperance pendant les annees 1824, 1825 et 1826' (1837). The map shows Port Jackson from the coast to Cockle Bay, highlighting the Ville de Sydney and Hyde Park, with a key showing thirteen other place names. Other geographical features include Ile Pinchgut, Neutral Harbour, Sirius Cove (present day Shell Cove) and Careening Cove (Mosman Bay). At the top right is a view of the entrance to Port Jackson. A note of the map says that the contours of the plan are the work of Commodore Hunter, the points marked by a letter were determined by the officers of the 'Thetis', and the contours of the middle ground were drawn based on the indications of the pilot Watson. "The relative crudity of the outlines, cf. Hunter's own maps, may indicate a limitation in the access given to Bougainville. While he made some visits in Sydney, it was out of bounds for his crew" (Brown).

The mapmaker
Hyancinthe Yves Philippe Potentien, Baron de Bougainville (1781-1846), was son of Louis-Antoine de Bougainville who had previously circumnavigated the world between 1766 and 1769. Hyacinthe's own circumnavigation, commissioned as a diplomatic mission to China by the duc de Clermont-Tonnere, was accomplished during 1824 and 1826. While in sydney he raised a monument to La Perouse.
