Magnifier used by Captain James Cook in the 1770s

The magnifier passed from Captain James Cook to astronomer William Bayly on Cook's last voyage. An assistant to the Astronomer Royal, Dr Nevil Maskelyne, Bayly was the Board of Longitude's appointment on Cook's second and third Pacific voyages. With fellow expedition astronomers he was responsible for the chronometers being tested on the voyage and scientific observations of earth's magnetic variation and gravity.
Despite the inscription on the elaborate silver case, the magnifier may not have been a gift. It is possible Bayly bought this memento when Cook's possessions were auctioned 'before the mast' following his death in Hawai'i in 1779. This was a common way of raising money for a dead sailor's family.

Relics of 'The Celebrated Navigator'
The magnifier passed from Bayly to his pupil and executor, Mark Beaufoy. It was probably Beaufoy's son who placed the magnifier in an engraved silver reliquary in 1844.
Cook was so famous his relics have been treated like those of a saint.
The veneration of Cook began soon after his death, when sailors made memorials for Cook's widow. 'Cook realia' — items connected to James Cook — have been keenly sought by collectors since the 1770s.
