Armillary sphere completed
The Song shi basic annals record that in the sixth lunar month of Yuanyou 7 (AD 1092), on the wuchen day, the armillary sphere and [celestial] image (渾天儀像) were completed.
What this does and does not establish
The Song shi is a Yuan-compiled (1343-45) official history drawing on Song court records; the English is an AI working translation. The one-line notice names no maker, place or design; the rendering of 渾天儀像 as 'armillary sphere and [celestial] image' is a working interpretation.

- Kind of record
- Placed in a year. A source places this in one year. It is listed under that year; no day precision is invented.
How it is dated
- Date reference
- 元祐 7 (元祐七年 as numbered by the annals), lunar month 6
- How we use it
- Year assigned from the lunar month under which the annals enter the item; the sexagenary day was not converted to a Julian day.
The date reference is this project’s reading of the source’s date. It may give an era name, a reign or a calendar in a normalised form rather than in the source’s own words; the dating notes say what the source prints.
