Williams Carlos Williams said that a poem is a machine made out of words. That’s a fitting way to describe Isabel Rogers’ poem ‘John’s Curious Machines’: a very efficient, inspired machine designed to evoke John Harrison’s ingenious marine chronometers. These highly precise clocks kept time even in rough, varied weather at sea, making it possible for a ship’s navigator to determine its longitude — saving many lives. Isabel’s poem recently won the Cardiff International Poetry Competition and she was one of the Live Canon Poetry Comp. shortlistees for the past two years. You can read ‘John’s Curious Machines’ on the CIPC website. She’s also written a guest blog for Royal Museums Greenwich about John Harrison and the Search for Longitude.
