Pair of Colonial theorem watercolours

Pair of Theorem watercolours. Hobart, 1836. Johanna Gorringe (1817 – 1864). Original Tasmanian myrtle frames. A very rare pair of early Tasmanian Colonial period watercolours, in the original native timber frames, the flowers taken from pattern book stencils, similar to American naïve work of the time. Johanna Gorringe arrived in Hobart Town in 1820 and died unmarried in 1864. These were painted by her at the age of 19. In 1860 she was committed to the Lunatic Asylum, New Norfolk and died 4 years after.
