Read the full account

The Canon of Kings lists reigns used to date astronomical phenomena in the Ptolemaic file. The dated chronology-list is not the Handy Tables’ computational lock and not the Almagest as kinematics. Ptolemy’s documented role is: A king-list used for dating observations is attached to the Handy Tables tradition. Later copies are carriers; unique autograph is not recovered. A king-list is a chronological instrument. Later editors, printers, and excavators remain named where they appear. Ptolemy's documented role is: A king-list used for dating observations is attached to the Handy Tables tradition.

Context

Babylonian and later reign-years, unnamed copyists, and later chronographers already sit in the list. A canon is not unique authorship of every later king. Later Livius pages are access. The public setting is the file around 0150-01-15. The instrument stays The Canon of Kings is a public chronological list attached to Ptolemy’s astronomical file. The setting of The Canon of Kings is a public chronological list attached to Ptolemy’s astronomical file is the public file around 0150-01-15. Driver personal-data-protection is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

That reading is an impact-path choice, not a property stored on the Fact itself.

Why it matters

Medium confidence on unique autograph. Welfare reading improving. The attached mechanism is A dated chronological list put public reign-years into the astronomical file, distinct from Handy Tables as a computational lock. Lag to any modern indicator is not treated as zero. This path is attached because the mechanism is named from this act, not because a driver list needed coverage. The welfare reading on this path is improving.

Shared responsibility is part of The Canon of Kings is a public chronological list attached to Ptolemy’s astronomical file. Naming Ptolemy does not delete co-authors, institutions, or later transmitters. The lag from 0150-01-15 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

What the sources establish

Britannica and Livius independently identify Ptolemy’s Canon as a distinct chronological list. Official: Britannica — Ptolemy, Canon of Kings (https://www.britannica.com/biography/Ptolemy (opens in a new tab); Encyclopaedia Britannica). Independent: Livius — Ptolemy’s Canon (https://www.livius.org/articles/concept/ptolemys-canon/ (opens in a new tab); Livius.org). The two URLs are different pages. Where the carrier is a later edition or a received narrative, that limit is stated rather than upgraded to an autograph. Official carrier: Britannica — Ptolemy, Canon of Kings (https://www.britannica.com/biography/Ptolemy (opens in a new tab); Encyclopaedia Britannica). Independent carrier: Livius — Ptolemy’s Canon (https://www.livius.org/articles/concept/ptolemys-canon/ (opens in a new tab); Livius.org).

Established: Canon of Kings as a Ptolemaic chronological heading. Not established: that Handy Tables is this same list. Established: a sourced public record of The Canon of Kings is a public chronological list attached to Ptolemy’s astronomical file under 0150-01-15.

If a number is not in the two records named above, it is not supplied here.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
