Collection of Historical Records
SN 1054 is one of eight supernovae that can be identified because written testimony describing the explosion has survived. In the nineteenth century, astronomers began to take an interest in the historic records. They compiled and examined the records as part of their research on recent novae, comets, and later, the supernovae.
The first people to attempt a systematic compilation of records from China were the father and son Biot. In 1843, the sinologist Édouard Biot translated for his father, the astronomer Jean-Baptiste Biot, passages from the astronomical treatise of the 348 volume Chinese encyclopaedia, the Wenxian Tongkao.
Almost 80 years later, in 1921, Knut Lundmark undertook a similar effort based on a greater number of sources. In 1942, Jan Oort, convinced that the Crab Nebula was the "guest star" of 1054 described by the Chinese, asked sinologist J.J.L. Duyvendak to help him compile new evidence on the observation of the event.

“Psychobabble is ... a set of repetitive verbal formalities that kills off the very spontaneity, candor, and understanding it pretends to promote. It’s an idiom that reduces psychological insight to a collection of standardized observations, that provides a frozen lexicon to deal with an infinite variety of problems.”
—Richard Dean Rosen (b. 1949)

“This seems a long while ago, and yet it happened since Milton wrote his Paradise Lost. But its antiquity is not the less great for that, for we do not regulate our historical time by the English standard, nor did the English by the Roman, nor the Roman by the Greek.... From this September afternoon, and from between these now cultivated shores, those times seemed more remote than the dark ages.”
—Henry David Thoreau (1817–1862)
“It’s always the generals with the bloodiest records who are the first to shout what a hell it is. And it’s always the war widows who lead the Memorial Day parades.”
—Paddy Chayefsky (1923–1981)
