Abstract

fetched live from OpenAlex

The intensification of agricultural production in the Fertile Cresent during the Early Bronze Age (EBA) is reflected in two farming tools: Canaanean blades, which were thinner than Neolithic blades; and the threshing sledge, into which some of these blades were inserted. In northern Mesopotamia, most Canaanean blades were long and wide, made by pressure using a lever and copper point, although some were narrower and produced by indirect percussion or by pressure with a crutch. In the Levant, however, although some wide examples have been recovered, narrow forms predominated. Controlled experiments have revealed that microwear on blade segments used in sledge inserts is different from microwear on segments used as sickles. This paper analyses samples of Canaanean blades and blade segments from Tell ʿAtij in northern Mesopotamia and Ein Zippori in the Levant to examine (1) whether wider and narrower Canaanean blade segments were used for different tasks, (2) whether some Canaanean blade segments were designed specifically to be inserted into sickle handles and used for harvesting and (3) whether sickle inserts were recycled and used in threshing sledges. We also discuss how production and use of Canaanean blades is related to EBA agricultural intensification.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
