Unearthing the Ancient City of Dadan (Full Episode) | Lost Treasures of Arabia | National Geographic

Scientific concepts / nature phenomena / historical discoveries mentioned

Archaeology, reconstruction, and surveying methods

• Reconstructing ancient civilizations from:
  • broken building remnants
  • refuse/dumps left by past people
• Chronology/phasing: determining how settlement organization changed over time (multiple phases).
• Site layout investigation: identifying entrances, walls, and urban organization through excavation.
• Epigraphy (inscription study): deciphering ancient scripts to infer identities, deities, and events.
• Epigraphic interpretation of funerary content:
  • identifying references to tombs, funerary monuments, and associated statues
  • interpreting curse/deity language as a protective or ritual element
• Archaeozoology: analyzing animal bones to infer ritual offerings (e.g., selected tibias tied to food offerings to protect tombs).
• Soil science / paleoenvironment reconstruction:
  • determining whether soil layers represent cultivated agriculture
  • inferring fertility and ancient farming supporting urban populations
• Photogrammetry:
  • multiple overlapping georeferenced photographs transformed into 3D models for recording/analysis.
• Taphonomy / preservation awareness:
  • careful excavation when bones are fragile and may crumble
  • understanding how environmental exposure affects deposits

Nature phenomenon affecting archaeology

• Rain-driven damage:
  • water infiltration can cause wall collapse
  • rain damages exposed archaeological layers, forcing teams to pause until soils dry
• Weather events explicitly described as torrent/pouring rain and post-rain assessment.

Key ancient civilizations, places, and inferred relationships

• Region and timeline
  • AlUla region (Saudi Arabia) with an ancient city of Dadan.
  • Dadanites followed by Lihyanites, roughly ~1000 BCE to 200 BCE (as stated).
  • Multiple occupants over more than 2,000 years, suggesting cultural/administrative changes.
• Neighboring powers and comparative chronology
  • Nabataeans: monumental sandstone tombs at Hegra (~20 km away) mentioned as later/after context (search focus is earlier kingdoms).
  • Minaeans (in Yemen): language/script found at/near Dadan (Minaic), described as associated with incense trade control.
• Dadan in historical/religious texts
  • Dadan mentioned in the Bible (Book of Ezekiel) as an important trading kingdom/nation.
• Trade-based state wealth
  • Wealth and prosperity linked to controlling parts of the incense trade route.
  • Incense origins emphasized as south Arabia (modern Yemen/Oman) and Horn of Africa, creating limited supply and high demand.
  • Minaean traders described as master merchants connected to incense routes (parallel to the “Silk Road” concept).

Funerary practices and religious life

• “Lion Tombs” (man-made rock-cut tombs)
  • holes/tombs carved into rock faces indicate that burial and afterlife beliefs were important.
  • graves described as empty (looting/destruction implied).
  • tomb size/carving effort suggests burial for wealthy/important residents.
• Quarry site inscriptions and expected tomb
  • Dadanitic inscriptions mention:
    • a tomb
    • funerary monuments and associated statues
    • “offering tables”
  • The offering table features:
    • a potential surface for solid and liquid offerings
    • a spout suggesting ritual pouring
  • Animal bones (tibias) interpreted as components of offerings.
• Religious function of a monumental staircase
  • A rock-carved staircase leading to a high peak is interpreted as religious, not economic (top reportedly lacks trade use).
  • Inscriptions cited as indicating worship of Minaean gods; described as an open-air sanctuary.

Urban infrastructure and resource management (water, access control)

• Water management / ancient technology
  • Identification of walls and an engineering achievement related to moving/handling water within a dense urban environment.
• Southern entrance and monumental walls
  • A long wall running east–west and an entrance framed by structures; ibex-related decoration/collapsed element noted, implying significant activity at that location.
• Checkpoints / access control
  • A nearby structure interpreted as a checkpoint controlling movement between city and mountain.
  • Economic rationale:
    • taxation on caravans traveling north/south
    • explains Dadan’s growth into a large city with monumental buildings and developed oasis agriculture.
• Agriculture supporting settlement
  • Soil analysis suggests palm-tree cultivation and fertile productive soils.
  • Ancient agricultural traces dated to >2,000 years, supporting large populations.

Warfare, defense, and political conflict

• Rock art as evidence of warfare
  • Rock art used to infer:
    • types of warriors (e.g., foot archer depiction)
    • weapon styles (bows, daggers)
    • possible tactics and how conflicts were imagined—information often missing in normal archaeological remains.
• Landscape and military strategy
  • Arid terrain and hills used for observation and hiding.
  • Horses described as major war animals for fast maneuvering.
  • Use of wheeled vehicles (chariots/carts) suggested as less suitable due to rough terrain.
• Defensive wall across a mountain pass
  • A massive wall (~4 meters high, ~85 meters long) built blocking a major valley, interpreted as defensive against large-scale threats beyond minor raids.
• Rivalry with Tayma
  • Inscriptions mentioned walls between Tayma and Dadan, suggesting competition for control of the northern incense branch.
• Shift in power and external conquest
  • New power hostile to the former dynasty, described as seeking to erase it.
  • Nabonidus of Babylon:
    • campaign in Northwest Arabia
    • killed kings in oasis centers including possibly the king of Dadan
    • outcome for Dadan unknown (destruction vs peaceful takeover speculated).

Major find: the elusive tomb

• Quarry excavations leading to a tomb
  • Discovery of a finger/hand protruding from stone layers → confirmed a burial in funerary context.
• Tomb implications
  • The tomb is expected to clarify burial practices and funerary rituals in Ancient Dadan.
  • Bone preservation poor; careful handling required.
  • Biological profiling (as planned):
    • determine age-at-death, sex
    • detect possible illnesses
• Stated osteological assessment
  • The deceased is described as an adult (at least ~20 years old).
