# The Almagest records dated observations from 127 CE under Ptolemy’s name

Date: 127

## The fact

The Almagest records observations dated from 127 CE under [Ptolemy](/people/ptolemy)’s name at Alexandria. The dated observing-span is not the missing autograph logbook heading and not the Hipparchus-reuse debate as a theft heading. Ptolemy’s documented role is: The Almagest lists observations from 127 to 141 at Alexandria. Do not twin this with pto-no-observing-log. Dated observations in the Almagest are not a surviving autograph notebook. Later editors, printers, and excavators remain named where they appear. Ptolemy's documented role is: The Almagest lists observations from 127 to 141 at Alexandria.

## Context

An Alexandrian observer, unnamed instruments, and later auditors already sit in the file. A listed observation is not a unique recovered diary. Later Toomer is access. Named others on the file: Unnamed instrument-helpers, later auditors of the dates, and neighbouring Hipparchus as a prior observer share the file. The public setting is the file around 0127-03-26. Unnamed clerks, soldiers, printers, or later editors may appear without becoming this instrument. The instrument stays The Almagest records dated observations from 127 CE under Ptolemy’s name. The setting of The Almagest records dated observations from 127 CE under Ptolemy’s name is the public file around 0127-03-26. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver edu-[digital-learning-access](/drivers/edu-digital-learning-access) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

Confidence is stated on the impact path, not hidden in adjectives. Do not twin this with pto-no-observing-log. Dated observations in the Almagest are not a surviving autograph notebook. Mixed effects of The Almagest records dated observations from 127 CE under Ptolemy’s name are separate paths.

## Evidence and sources

Britannica independently dates Almagest observations from 127, distinct from a missing autograph log. Official: Britannica — Ptolemy, observations 127–141 CE (https://www.britannica.com/biography/Ptolemy; Encyclopaedia Britannica). Independent: Britannica — Almagest, dated observations (https://www.britannica.com/topic/Almagest; Encyclopaedia Britannica). 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, observations 127–141 CE (https://www.britannica.com/biography/Ptolemy; Encyclopaedia Britannica). Independent carrier: Britannica — Almagest, dated observations (https://www.britannica.com/topic/Almagest; Encyclopaedia Britannica).

## Significance

Improving education-access path: public dated observations in a surviving treatise. Medium confidence on unique autograph. Welfare reading improving. The attached mechanism is A dated observing-span put public numerical astronomy into a teaching file, distinct from the no-observing-log gap as a missing autograph book. 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.

The welfare reading used in this dossier is improving. That reading is an impact-path choice, not a property stored on the Fact itself.

## What is established and what is not

Established: dated 127–141 observations in the Almagest. Not established: that a lost notebook is this same object. Established: a sourced public record of The Almagest records dated observations from 127 CE under Ptolemy’s name under 0127-03-26. Established: a sourced public record of The Almagest records dated observations from 127 CE under Ptolemy’s name under 0127-03-26.

Shared responsibility is part of The Almagest records dated observations from 127 CE under Ptolemy’s name. Naming Ptolemy does not delete co-authors, institutions, or later transmitters. The lag from 0127-03-26 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.

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.
