From Byron's Don Juan:
The Senhor Don Alfonso stood confused;
Antonia bustled round the ransack'd room,
And, turning up her nose, with looks abused
Her master and his myrmidons, of whom
Not one, except the attorney, was amused;
He, like Achates, faithful to the tomb,
So there were quarrels, cared not for the cause,
Knowing they must be settled by the laws.
What is the meaning of the words in bold? I read about Achates, and probably he was faithful to some tomb in the Aeneid, but what is the meaning of so there were quarrels? I cannot understand it..
