Translation of "Sapling" in Portuguese

Thither I drew, and strove with eager hold / a green-leaved sapling from the soil to tear, / to shade with boughs the altars, when behold / a portent, weird to see and wondrous to unfold!

Para adornar com verdes ramos os altares, / aproximo-me e trato de arrancar, / do chão, viçoso arbusto. A um prodígio espantoso / então assisto (mas quem pode acreditar?).

Once more / a limber sapling from the soil I tore; / once more, persisting, I resolved in mind / with inmost search the causes to explore / and probe the mystery that lurked behind; / dark drops of blood once more come trickling from the rind.

Sondando as causas misteriosas do portento, / procuro de outro arbusto arrancar tenro galho / e da casca também goteja o sangue impuro.
