Unfortunately, Thomas wasn't the kind to write down the entirety of his life in a journal, the records are sparse, and mostly utilitarian - reminders to himself about various events, local, social and astrological. Two consecutive entries separated by a year read "Giles ran away" and "Giles has returned".
At one point, the entries become much denser, and appearr to be construction logs for the observatory in the Watchman's tower. There are intricate diagrams of lenses, and also a few notes regarding how all lensmakers are incompetent.
The construction is finished in 1576. Entries from 1577 are notably more animated:
"A Great Comet hath visited our Sky Above, a smoking star, a dazzling cloud."
"Wind, Moon, and Shell in the Heavens Inferior were known to Thomas of the Black Dove. My predecessor knew this Truth - three Blossoms hath the Watchman's Tree: Paper; Ink; and Flame. The Great Comet, I now aver, is that Flame. I shall call the Dream of a Star to me tonight, shall the night permit me."
The excited tone slowly fades, returning to the style similar to earliest ones.
