"...We once were Trojans, once this was faire Troy,
And Trojans grace: now angrie Iove our joy
Gives to the Greeks: Greeks lord it over us,
Out citie fir'd, we most calamitous.
The hiddie horse standing within our town,
Hath armed men disgorg'd: fire up and down
Sinon triumphant throws: some strongly stand
To keep our gates wide ope:ne're did our land..."
