Following Osiris: Perspectives on the Osirian Afterlife from Four Millennia (Smith, 2017)
Mark Smith (Professor of Egyptology, University of Oxford) provides the most comprehensive scholarly diachronic study of Osiris and the Osirian afterlife concept available, tracing it from prehistoric Egyptian burial customs through the fifth century CE. The book is published by Oxford University Press and reviewed in the Journal of Near Eastern Studies (vol. 78, no. 1, 2019). Smith surveys five major periods of significant change in how Egyptians conceptualized the relationship between Osiris and the deceased. Chapter 3 — "Unreading the Pyramid Texts: So Who is Osiris?" — is directly relevant to the question of earliest attestation.
"The earliest secure evidence for belief in Osiris dates back to the Fifth Dynasty (c. 2494–2345 BCE)." (Smith 2017, p. 19)
The Pyramid Texts do not contain a sequential narrative of the Osiris myth; instead, scattered utterances presuppose an audience familiar with the myth's basic outline — the murder, the dismemberment, the reconstitution by Isis, the posthumous birth of Horus. Smith argues this presupposition is evidence the myth's oral antecedents substantially predate the physical texts, but that their exact horizon cannot be archaeologically fixed. (Smith 2017, ch. 3)
Earlier Old Kingdom sources (4th Dynasty and first half of 5th Dynasty) show the deceased king identified with Re and Horus but show no secure Osirian identification — the Osirian complex appears to crystallize specifically in the 5th Dynasty. (Smith 2017, pp. 61–80)
The transition from royal exclusivity (Pyramid Texts, royal tombs only) to a democratized Osirian afterlife (Coffin Texts, Middle Kingdom) represents a major structural shift in both function and social reach of the belief system. (Smith 2017, ch. 5)
Smith is one of the most authoritative living scholars on Egyptian religion and funerary literature. This is an academic monograph from a major press, peer-reviewed. Caveats: (1) Smith's Chapter 3 title ("Unreading the Pyramid Texts") signals his critical distance from interpretive traditions that read a coherent Osiris narrative into these texts — some Egyptologists (e.g., Hornung) read a fuller myth where Smith sees only allusion. (2) The 5th-Dynasty "earliest secure evidence" claim is textual — pre-5th-Dynasty archaeological or iconographic material might exist but has not been conclusively identified with Osiris specifically. (3) The very long chronological scope (four millennia) means individual period analyses are necessarily selective.
