Abstract
Summary A copper‐alloy thimble was found in 2010 at Punta Secca, Sicily, in a sealed context datable by coins to the first quarter of the seventh century AD. It has generally been thought that thimbles did not reach the Mediterranean area until the ninth century AD, but at least nine metal examples are in fact attested at various places from contexts datable between the late sixth century and the early ninth. It is suggested that the increasing use of silk in clothing in the Byzantine Empire during the seventh century, probably accompanied by the use for the first time of steel needles which made the use of a finger protector imperative, explains the apparent introduction of thimbles at this time. No securely dated metal thimbles are known from sites of Roman date, except for one at Ephesus of c.AD 100. It is very tentatively suggested that this last example might represent an import from China, where thimbles (and steel needles) are attested from at least the third century BC onwards.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
