Eclipse
The covering of sun or moon by shadow. Some archives treat the event as an omen; others treat it as a calculated recurrence.
Mesopotamian tradition
Eclipse is associated with Prophecy.
Mesopotamian omen series treat lunar and solar eclipses as signs that can be read for king and land. That is a cuneiform technical literature, not Ptolemy’s natal craft.

Eclipse appears in Mesopotamian tradition.
Eclipse omens are a known Mesopotamian genre. They sit beside, not inside, the Gilgamesh flood story.

Eclipse is associated with Omen.
Where an eclipse is treated as a sign, it is an omen. Mesopotamian series and later handbooks disagree on what it signs.

Astrology
Eclipse is used in Astrology.
Ptolemy treats eclipses among celestial conditions that modify judgments. The handbook is Hellenistic, not Babylonian omen series copied wholesale.

Eclipse is associated with Shadow.
An eclipse is a covering by shadow. The physics is one fact; the omen is another.

Eclipse is used in Calendar.
An eclipse cuts a hole in the named day. Calendars that keep the covering remember it as a mark in time — a dark appointment the year must still account for.

Moon is associated with Eclipse.
A lunar eclipse is the moon entering shadow. Cultures differ on whether that covering is an omen, a calculation, or both.

Sun is associated with Eclipse.
A solar eclipse is the sun covered. Mesopotamian omen literature treated some such coverings as signs; that treatment is not universal.

Nahua tradition
Eclipse appears in Nahua tradition.
Sahagún’s Florentine Codex records sun/moon covering speech in Book 7 eclipse speech — named eclipses among sky omens and events. A colonial-era Nahua ethnographic attestation, not a pan-Mesoamerican essence and not an unfiltered pre-invasion voice.

Hellenic religion
Eclipse appears in Hellenic religion.
Herodotus narrates the eclipse that interrupted the Median–Lydian war, tied to Thales’ prediction speech. A named eclipse in that traveler’s speech, not Nahua Florentine eclipse alone and not a modern astronomy dump.

Penumbra is historically related to Eclipse.
Ptolemy’s Almagest Book VI seats the partial shadow fringe around the dark cone when eclipse shadow geometry is set out for sun and moon. A named penumbra continuous with that partial-shadow neighborhood, not umbra the dark core (left to unpublished cosmos-2 claim) and not twilight as sky-light.

Partial eclipse is historically related to Eclipse.
Ptolemy’s Almagest Book VI seats magnitudes of obscuration when only part of the sun or moon is covered among eclipse computations. A named partial-eclipse continuous with that partial-cover case, not totality and not penumbral-eclipse as the fringe-only lunar case.

Totality is historically related to Eclipse.
Ptolemy’s Almagest Book VI seats the duration when the sun is fully covered or the moon is fully in the umbra among eclipse timing computations. A named totality continuous with that full-cover interval, not partial-eclipse and not Bailey/diamond-ring contact chrome refused here.

Saros is historically related to Eclipse.
Ptolemy’s Almagest seats long eclipse-return periods in the lunar and eclipse chapters that bring similar sun–moon–node geometry around again — the cycle later called saros in English. A named saros as continuity on that eclipse-period path, not a civil calendar month alone and not eclipse as a single event dump.

Roman religion
Eclipse appears in Roman religion.
Pliny’s Natural History seats eclipses among Book 2 coverings of sun and moon. A named eclipse in that encyclopedia, not omen-only prophecy dump and not Ptolemy judicial eclipse alone.
