Where do they actually overlap?

Common questions

Are Nephthys and Set the same figure?

These two are set against one another in the texts, which is itself a claim worth attributing. His wife, who takes her sister's side. 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, Nephthys or Set?

Set is the older name: first attested around c. 3000 BCE, against c. 2600 BCE for Nephthys. Where the two dates are far apart, that gap is the whole reason the pair is worth comparing.

Do any texts name both Nephthys and Set?

Yes — 3 texts name both. A single text naming both figures is the strongest evidence available here that its author treated them as distinct, whatever later writers did with the pair.
