Rescue assemblage from a Deccan rock-shelter: dating and display without lab reports
A district museum in Maharashtra has eight weeks to open a gallery using material from a rescue excavation beside a painted rock-shelter. The assemblage includes 14 microliths (blades, flakes, a crescent), three lumps of red ochre, a red-slipped potsherd painted with a horned stick figure, and a broken red-sandstone fragment with a carved lotus petal. There are no radiocarbon dates, the excavation notebook is incomplete, and the shelter's painted panel was recorded only in photographs. The curator wants to label the whole case 'Mesolithic rock art, 10,000 BCE' because school groups respond to that phrase. The education officer worries that the potsherd may be much later and that the sandstone fragment may be architectural. The museum has a small budget for one analytical test and a bilingual label (Marathi/English).
1. Decide whether the four material groups can be presented under one chronological label. Give the reasoning you would use and specify a safer label hierarchy.

Reasoning. The four groups are not one assemblage in the same sense. Microliths and ochre are portable artefacts that may indicate prehistoric occupation, but without stratigraphy they cannot date the rock paintings. The painted potsherd is a ceramic industry product; horned figures occur from the Chalcolithic into the early historic period, so it cannot be used to date the shelter. The lotus-petal sandstone fragment is architectural and may be Buddhist or Hindu, therefore later than the prehistoric use.
Safer label hierarchy.
- Main panel: 'Occupation and art at the site: prehistoric to early historic' - explicitly a provisional range.
- Sub-panel A: 'Stone tools and ochre: prehistoric occupation (date uncertain)'.
- Sub-panel B: 'Painted pottery: later settlement (date to be confirmed)'.
- Sub-panel C: 'Architectural fragment: religious building, date uncertain'.
Do not place the potsherd inside a 'rock art' case. Rock art is fixed to the shelter wall; the sherd is a portable painted object. This distinction protects against a false equation of all painted images.
2. The curator proposes calling the horned figure 'a prehistoric shaman'. What is the evidentiary problem, and how would you word the label to stay defensible?

Problem. Calling the figure a shaman converts an identification into a religious interpretation. The image is a stick figure with horns; horns appear on animals, deities, and human costumes in many periods. There is no associated ritual deposit, no stratigraphic date, and no contemporary text. Ethnographic analogy with living communities is not proof for a prehistoric object.
Defensible label. 'Painted potsherd with a horned figure. The meaning is unknown; the figure may represent a human, animal, or supernatural being. Date from ceramic style and context: provisional.' Add a question: 'What other evidence would you need?' This is honest and teaches inference. If the museum wants interpretation, put it on a separate 'interpretations' panel, not on the object label.
3. Which single analytical test would you prioritise, and what records must be completed before the opening?
Read the worked answer
Priority test. If any charcoal or organic temper is present, AMS radiocarbon on a single fragment gives the strongest independent date. If not, thermoluminescence on the potsherd can estimate its firing date, but it requires sampling and may not be permitted on a small sherd. pXRF would identify ochre composition but not chronology, so I would not spend the only test on it.
Records before opening. Complete a context sheet for each group: findspot, depth, associations, photographs with scale, drawings, condition, weight, and conservation history. Interview the excavator and deposit the notebook. Label all dates as provisional. The unglamorous record work is what prevents the '10,000 BCE' label from becoming permanent.
