Pulley from long-case clock made by Ahasuerus Fromanteel, London, 1660-1665.

The Fromanteel family produced the first pendulum clocks in England, following the visit of Fromanteel’s son John to Holland (Netherlands). He learned to make these new clocks from Salomon Coster who had an agreement with Christiaan Huygens to use his idea. Clocks now became accurate enough to have minute hands.
