John Harrison and the search for longitude
by isabelrogers
The National Maritime Museum in Greenwich asked me to write a guest blog for them, because of my poem John’s Curious Machines. They currently have an exhibition running called Ships, Clocks and Stars, which tells the story of John Harrison and his chronometers – among a lot of other history about the search for longitude. They also have all five of John’s clocks on display: a rare event. If you can, do get along to Greenwich to have a look at them. It’s on until January.
My guest blog about how I came to write my poem and how it relates to those extraordinary machines is here.

Fabulous — it’s a wonderful place and a magical story, we went last year as a family (blogged) and all enjoyed it.
Just read your blog – aren’t they wonderful to see? To stand and look at all five (they’ve brought the fifth in for their current exhibition) was quite special.
The dedication required to make them was epic — it took most of his life, and also there’s a cross-fertilisation of stories. Nevil Maskelyne’s work (some of which is available as Google/Amazon reprints?) is fascinating in its own right.
