Abstract
Operatic and theatrical historians in both Brazil and Portugal frequently mention that around the last quarter of the 18 th century, Queen Maria I forbade women to perform on public stages in Portugal. However, it seems that the impresarios and owners of opera houses in colonial Brazil were unaware of this prohibition, since I have found several references to actresses performing in many of the permanent theatres at the end of the 18 th century and the first decades of the 19 th century. The great majority of these actresses were half-caste women. The most remarkable example is the case of soprano Joaquina Lapinha, prima donna of the Opera Nova in Rio de Janeiro, and probably the only native Luso-American singer to perform in a European theatre in the 18 th century. This article considers the employment of actresses in the opera houses of São Paulo, Vila Rica, Rio de Janeiro, and Porto Alegre, showing how the impresarios of these public theatres managed to provide their companies with the necessary human resources.

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.
