Beneath a flinty church tower deep in the Kent marshes, ‘among putrid estuaries and leaden waters’, lies a monument to an Elizabethan man of business. It is not much to look at. David Howarth calls it ‘second rate… dull’ and ‘strangely provisional’, despite its expanse of glossy alabaster. Moreover, the name of the man commemorated will ring few bells, even among historians.
