Object history | Captain Cook is said to have given this magnifier to William Bayly, astronomer on board the HMS Discovery during Cook's third voyage to the Pacific from 1776-79. The magnifier attests to the significance of Cook and his voyages in the British, and subsequently the Australian, imagination. The magnifier documents the role of William Bayly, assistant to the Astronomer Royal, who sailed on the second and third of Cook's voyages, and visited Australia twice. | |||||||||||||||||||||||
