Abstract
From Strabo we learn that Xenarchus was originally from Seleucia on the Calycadnus in Cilicia Tracheia, but that he spent most of his life away from home, teaching philosophy first in Alexandria, then in Athens, and finally in Rome [T1]. Strabo adds that he himself attended Xenarchus’ lectures. Finally, he names two people that must have been very important in Xenarchus’ life: Arius and the emperor Augustus. Arius is Arius of Alexandria, a philosopher who may have been the same person as the doxographer Arius Didymus and the Stoic philosopher listed on the index locupletior to Diogenes Laertius’ Lives. Arius was not only a friend, a teacher, and a confidant of Augustus; he was also a senior political advisor and a very influential member of Augustus’ most inner circle. Strabo seems to suggest that the friendship with Arius played a significant role in Xenarchus’ career. More directly, it is possible that Xenarchus owed his friendship with Augustus to Arius. On the basis of this biographical information, we can date Xenarchus’ activity to the second half of the first century bce.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
