**Reanalysis of 2,869 flint artefacts from Heliopolis, kept in Turin since the 1903–1906 excavations, suggests specialised blade production for other villagers before the Egyptian state.**

Researchers from the Istituto di Scienze del Patrimonio Culturale (CNR ISPC) in Rome, led by Francesca Manclossi, reanalysed 2,869 flint artefacts from Heliopolis, according to a study in the Journal of Anthropological Archaeology. Most of the pieces come from excavations of 1903–1906 and have since been stored in 40 wooden boxes at the Museo Egizio in Turin. [1] The authors interpret the material as evidence of a specialised workshop in Lower Egypt during the Predynastic period. [1]

## Cores, blanks and reduction methods

Unlike many historical collections, this one contains not only finished tools but also cores, blade blanks and flakes. From the knapping traces, the archaeologists reconstructed how cores were prepared, blades removed and then finished into tools. They found several reduction strategies within a broadly shared technical tradition. [1] Old labels, inventory numbers and excavation records were used to check the origin of the pieces.

For comparison, the team used 2,546 stone artefacts from Area 251, about 500 metres away, excavated in 2019. It contains Predynastic deposits near a structure interpreted as a brewery, and the material was sieved systematically, so fine debris survived. [1]

## Specialists and users

The older collection has 187 blade cores against 549 blade blanks and tools. Many cores, however, carry scars of considerably more removals, so a substantial share of the blades probably left the workshop, possibly for elsewhere in the settlement. [1] Area 251 yielded only 14 such cores but 284 blades and tools made from them. Its cores were prepared less carefully and show more failed strikes, which suggests skilled knappers in a workshop area and occasional, less practised production elsewhere. [1]

The authors link this pattern to “arbitrary craft specialisation”, in which expertise was unevenly distributed and context-dependent rather than institutionalised. Specialists may also have worked in agriculture. Blanks were made by experts, while retouch and maintenance were mostly done by the users, judging by varied edges and working traces. [1]

The study sets out limits. The distribution of finds does not show centrally controlled production, and the two collections are not directly comparable in all proportions because of different excavation methods, find areas and preservation. The workshop therefore remains a well-founded interpretation, not a directly proven production site. [1]

Hammamiya knives, with standardised forms known from several regions of Egypt, point to wider links. Individual cores and rough pieces suggest they were at least occasionally made in Heliopolis. Whether local craftspeople imitated outside models or itinerant specialists worked there remains open. [1]
