Firstly, to avoid any confusion, Ringmer's Timothy tortoise is not the tortoise who died in 2004 and was dubbed 'Britain's oldest pet', despite some similarities. As well as having the same name, both tortoises were originally assumed to be male but were later shown to be female. In addition, it's likely that both were some kind of ship's pet before they reached England.
Our local Timothy was born in the 18th century - possibly around 1740 - by Henry Snooke, who brought it home to Ringmer. Mr Snooke gave the tortoise to his wife, Rebecca, who was the aunt of naturalist Gilbert White. When Rebecca died, Gilbert took her tortoise home with him to Hampshire, writing about the tortoise in his book 'The Natural History and Antiquities of Selborne'.
The other Timothy, who ended his days in Devon, was born in the mid-19th century and has his own well-documented biography called simply 'Timothy the Tortoise'.
Henry and Rebecca are apparently buried together in Ringmer's parish church. Timothy, meanwhile, rests at the Natural History Museum in London.
My biggest surprise was discovering that Timothy may not have been the first tortoise in Ringmer. In 1774, Gilbert White wrote to his brother John, describing the differences between Timothy and other types of tortoise:
There are tortoises whose shells are always open behind and before "apertura testae anterior," as he says himself, "pro capite et brachiis; posterior pro cauda et femoribus." These apertures are supported, as it were, by pillars on each side and can never be closed. Of such construction is the shell of Mrs Snooke's present living tortoise, Timothy. But then there are tortoises whose under shell has a cardo, an hinge, about the middle of their bellies, commanding one lid or flap forward, and one lid backward (like the double lidded snuff-boxes) which when shut conceal the head and legs and tail of the reptile entirely, and keep out all annoyances. Two such (very small they were) Mrs Snooke had formerly; and the shells lie still in her room over the hall.Although we can't be certain these tiny tortoises were born before Timothy, it's certainly possible that Timothy was bought as a replacement or even a companion for these creatures.
But it's Timothy that's remembered locally, with his likeness appearing in a number of places, including the village sign.
