From Byron's Don Juan:
While this high post of honour's in abeyance,
For one or two days, reader, we request
You'll mount with our young hero the conveyance
Which wafted him from Petersburgh: the best
Barouche, which had the glory to display once
The fair czarina's autocratic crest,
When, a new lphigene, she went to Tauris,
Was given to her favourite, and now bore his.
What is the meaning of the last line? It gravels me. I don't understand what's going on there.
The crest symbol was given to the favorite of Catherine the Great? So that he could display it on his vehicles? But what is " .. and now bore his"? Now the barouche bore the coat of arms belonging to Don Juan's family?
I googled and found a footnote to "favorite", but that footnote does not explain the meaning of the line to me:
