Side by side, from the sources

Osiris vs Yama

These two are identified with one another in the record, which is not the same as being the same figure. Both are the first to die and so become the sovereign judge of the dead.

Deity · Egyptian · c. 2600 BCE

Osiris

also called Wesir, Asar

Murdered by Set, reassembled by Isis, and installed as judge of the dead. He is the earliest fully developed dying-and-rising sovereign we have.

Where do they actually overlap?

Texts naming both

None. The two never appear in the same text in this corpus, which is worth knowing before accepting any confident claim that they are one figure.

Common questions

Are Osiris and Yama the same figure?

These two are identified with one another in the record, which is not the same as being the same figure. Both are the first to die and so become the sovereign judge of the dead. ColossiansOne records the link rather than asserting the identity: where texts disagree about whether two names denote one figure, the disagreement is what gets shown.

Which is older, Osiris or Yama?

Osiris is the older name: first attested around c. 2600 BCE, against c. 1400 BCE for Yama. Where the two dates are far apart, that gap is the whole reason the pair is worth comparing.

Do any texts name both Osiris and Yama?

No text in this corpus names both. That is not proof they were considered the same figure, but it is why the identification has to be traced through the scholarship rather than read off a page.
