Question

que le implora don diego al rey con la llegada del duque octavio a sevilla?​

Answer 1

"Who cares Don Diego to the king with the arrival of the Duke Octavio to Seville" hope that helps

Answer 2

I am afraid the previous response was not entirely correct.

The question is “What is Don Diego begging the king to do upon the arrival of the Duke’s arrival in Seville?”

He’s asking him to grant him the right to duel.
