In breaking news, in this post Charles Wesley’s encrypted journal cracked after 250 years
the shorthand of Charles Wesley was decoded by reference to the scripture verses which he had included in his journal. The full story is here
Wesley's shorthand, which omits vowels and abbreviates consonants, is a highly personalised adaptation of that invented by John Byrom, the 18th century poet, diarist and stenographer. Byrom, whose method was taught at Oxford University, published his New Universal Shorthand in 1740. Wesley's is severely abbreviated, sometimes using a string of consonants without breaks. Whole sentences are elided and the spellings are often phonetic. The language generally is that of an 18th century gentleman and preacher. ...
The breakthrough came when he discovered that Wesley had rendered part of the scriptures in shorthand and was able to compare the abbreviations against the King James Bible. “I was determined to unlock it. Charles was a great man, with insights that remain important for us today,” he said.
