Fingerprints at Boncuklu: looking closely at clay

A historical research story

The earlier Boncuklu website introduced Dr Lori Hager’s work on fingerprints preserved on clay objects. The account survives in an archived snapshot captured on 12 November 2020. That is the capture date, not a verified original publication date. Its image paths associate the material with the project’s 2014 uploads. This page provides a new explanation of the subject rather than silently presenting the old field notice as current news.

A fingerprint impression can bring the making or handling of an object into focus. It is a physical trace, but it does not arrive with a name, social role or complete biography attached. The first questions concern what is preserved, the object’s context and how the surface can be examined consistently.

What RTI does

Cultural Heritage Imaging explains Reflectance Transformation Imaging, or RTI, as computational photography using a fixed camera and photographs made with light from different directions. A model of reflectance lets a reader change virtual illumination and enhance surface detail. It is not, by itself, a complete geometric 3D mesh that can be freely viewed from every side. A static enhanced image is one rendering of that model, not the full interactive dataset.

Seeing a trace is not identifying its maker

The historical story linked ridge observations with questions about who made the impressions. An updated account should keep those as questions requiring a documented analytical basis. This page does not assign a definite sex or age to an individual print, and does not repeat the earlier promise that a simple visual inspection would resolve every case. Preservation, measurement and comparison must be considered before an interpretation is reported.

How to read an enhanced image

Compare ordinary colour with an enhanced view and note which features become easier to see. Enhancement can assist observation, but the interpretation still needs the original object record and an explanation of the method. A colour-coded normals view should not be mistaken for the object’s original colours.

For a broader framework, read evidence and interpretation and early clay technology. The connection is practical: an object can preserve evidence of manufacture, handling and later processes, and each deserves a distinct question.
