General contextHenshaw's early life was heavily influenced by the civil war and upon his return to England, he sought scholarly and intellectual pursuits in favour of life in the public eye. He associated closely with John Evelyn (FRS 1663), alchemist Thomas Vaughan, Robert Child, as well as Elias Ashmole (FRS 1661). While Henshaw himself did not publish any alchemist works, his library was used by Ashmole for the latter's 'Theatrum chemicum' (1652) and 'The Way to Bliss' (1658). He also corresponded with Samuel Hartlib through loosely-established 'Christian Learned Society'.
