An Unsolved Cipher

What does this say? It’s an excerpt from a small bound volume given in 1841 by Harvard law professor Theophilus Parsons Jr. to John Davis of the Massachusetts Historical Society. Davis noted, “It was found in his father’s Library after his decease, its origin and contents unknown. I hoped to find some person of sufficient skill in stenography, to decipher the pages. But it is still, to me & those whom I have consulted, a Sealed Book.”

It seems to be a dated record of some kind. The anonymous writer used Arabic numerals, so we can see that the entries are organized by year, month, and day, with long entries on one side of each page and shorter ones on the other.

But no one has ever determined its meaning. It was conjectured that the volume might be the diary of a clergyman, perhaps Theophilus’ father, the Rev. Moses Parsons of Byfield, but the entries extend to 1799, 16 years after Moses’ death.

For now the diary (if that’s what it is) is kept at the Massachusetts Historical Society. MHS reference librarian Jeremy Dibbell writes about it here.
