Most of you know the rules; if you are new, here's the short version:
1. Don't blurt out the answer. Leave a witty remark in the comment section that paraphrases, disguises or hints to your guess. I'll judge if you were right.
2. Don't point fingers at others and laugh. ( a treat reserved for the host of this blog and yellow budgies!)
3. Don't finish the cookies!
let's go...

A man born in London in 1633. He started to write a diary in 1660 and continued writing it until 1669, I guess he had a lot to say. Bad eyesight stopped him to continue. In fact, his diary gives us insights into his time, hello!...things like The Great Plague and the Great Fire of London were causing havoc and he also buried a big cheese we are told, to protect his house from catching fire. I guess he had his reasons, perhaps bad eyesight!
More interestingly, he wrote in letters that looked like a code and was referred to as Shelton's shorthand. He died in 1703, probably not of glaucoma.

Who's the man? Now of to the comment section with you and let the fun begin!
HINT away!
