Translation of "Talham" in English

Áreas elegem / da corte de justiça e do augusto senado. / Aqui se draga o porto, ali se assentam / profundos alicerces para um teatro, / ou se talham do mármore colunas / imensas destinadas a adornar / o magnífico palco projetado.

Those clothe with awe / the Senate; there they choose the judges for the law. / These delve the port; the broad foundations there / they lay for theatres of ample space, / and columns, hewn from marble rocks, prepare, / tall ornaments, the future stage to grace.
