Is this a `Converbâ„¢'?

Question

Her deck stacked high with silver, gold, and knaves:

Thus diamond queened Britannia ruled the waves.

Answer 1

Britannia...as in Great Britain?  If I'm reading it correctly, I can see a Con-verb in this.  After all, it takes wealth in order to rule the waves and invade other countries in the days of old.  

This is my assumption since a Con-verb is supposed to be controversial.

They've added a dash now so that the poetic Con-verb won't be mistaken for the grammatical converb.
