ERITREA / Publication of the archaeological chronology, not a single destruction date

Adulis: why did the Red Sea port lose its role?

An important trading port survives as archaeological deposits. New excavations complicate the idea that a single event explains its decline and abandonment.

Author: EklipsisEdition 1 · 2026-09-302 source entries3 inspector tasks

Adulis, near Zula, Eritrea · Approximate orientation marker for the named locality, not an exact encounter, burial, ritual or excavation position.

Assessment: Adulis's changing occupation is documented; one exclusive cause and date for its loss of importance are not established by these sources.

Investigation and inspector’s assessment

The mystery and the documented account

Zazzaro, Cocca and Manzo's 2014 report describes stratified excavations begun in 2011, reconstructing occupation through pottery and architectural change. Its introduction connects Adulis with changing Red Sea trade while explicitly leaving the ultimate causes of abandonment uncertain. A preliminary account of church excavations in 2018–2019 identifies several building phases and later Islamic reuse after the building ceased functioning as a church. That later activity matters: abandonment of one function is not identical to the disappearance of every inhabitant. [S1] [S2]

The question worth investigating

Did trade decline, environmental change and altered building use occur together, or in different phases? What securely dates the final use of each excavated area?

Evidence, provenance and uncertainty

Only investigated deposits support the reported sequence. The 2018–2019 church interpretation is preliminary and available here through its institutional abstract. Religious and commercial transitions do not establish a single conquest or citywide catastrophe. [S1] [S2]

Inspector’s assessment

Adulis's changing occupation is documented; one exclusive cause and date for its loss of importance are not established by these sources.

Next research and discriminating evidence

Compare stratigraphy, pottery dates and reused buildings by excavation area. Treat ancient literary references separately from material evidence. Require matched dates before linking local damage to a region-wide political event.

Documentary chronology

  1. 2011

    The team's stratified excavations begin. [S1]

  2. 12 June 2014

    The chronology report is published online. [S1]

  3. 2018–2019

    Church excavations document multiple phases and later reuse. [S2]

  4. 30 September 2026

    Eklipsis compiles this English documentary investigation from the named sources. No field visit or new eyewitness interview is claimed.

Dates distinguish the event, the creation of a record and its later publication. Approximate dates remain approximate.

Hypothesis review

Changes in trading networks and political relationships

Historical hypothesis

Supporting considerations
The port participated in wider Red Sea exchanges.
Limits and objections
Temporal association alone does not establish the local cause.
Discriminating test
Compare securely dated imports and settlement phases with other ports.

Uneven decline and reuse across different areas

Archaeologically testable alternative

Supporting considerations
The later church report records changed use rather than a simple terminal phase.
Limits and objections
One building cannot represent the entire town.
Discriminating test
Compare final-use deposits and later occupation across additional excavated areas.

Inspector’s next steps

  1. Trace the earliest accessible record

    For Adulis: why did the Red Sea port lose its role?, record author or storyteller, collection date, language, translation, page and exact scope. Distinguish evidence of a story being told from evidence of its events. Note which full documents remain unavailable.

  2. Investigate the central question

    Compare stratigraphy, pottery dates and reused buildings by excavation area. Treat ancient literary references separately from material evidence. Require matched dates before linking local damage to a region-wide political event.

  3. Compare explanations without merging evidence

    Compare securely dated imports and settlement phases with other ports. Compare final-use deposits and later occupation across additional excavated areas. Preserve contradictions and unsuccessful searches; proposed work remains unperformed.

These are proposed research tasks, not completed fieldwork or requests already sent to an archive.
