John Keay The Great Arc:
the dramatic tale of how India was mapped
and Everest was named
HarperCollins 2001 (2000)
At the edge of the Welsh town of Crickhowell in the Black Mountains of Wales lies the Georgian manor house of Gwernvale, now a hotel. It was built by Greenwich solicitor William Tristram Everest, and local lore claims that his eldest son George was born here: his baptismal certificate attests that he was born on the 4th July 1790, but there’s no supporting evidence as to where. As it was not till several months later that he was baptised at St Alphage church, Greenwich — on 27th January 1791 — the legend appears plausible until one considers the likelihood that the present building was only constructed between 1797 and 1803. Be that as it may, there is a neatness about George Everest’s possible connections with the Black Mountains and the mountain named after him in 1865, with the added irony that he never actually set eyes on the world’s highest summit.

The Arc closely followed the meridian 78° east of Greenwich, spreading its triangulated tentacles east and west in its effort to accurately map the whole of British India, from Cape Comorin in the south to the Himalayan foothills in the north and beyond. The rate of attrition for the army of surveyors, their assistants and support was equivalent to the decimation of an army over its half-century of existence; malaria, fevers, animal attacks and sheer exhaustion exacted a heavy price for the inch-perfect survey.
The epic story of Lambton, Everest, their assistants and successors as told by John Keay is one of slow but steady success despite Continue reading “A mountain to climb”
