Deem ye what bounds the rival realms divide?
Or e'er the jealous queens of nations greet,
Doth Tayo interpose his mighty tide?
Or dark sierras rise in craggy pride?
Or fence of art, like China's vasty wall? -
Ne barrier wall, ne river deep and wide,
Ne horrid crags, nor mountains dark and tall
Rise like the rocks that part Hispania's land from Gaul

XXXIII.

But these between a silver streamlet glides,
And scarce a name distinguisheth the brook,
Though rival kingdoms press its verdant sides.
Here leans the idle shepherd on his crook,
And vacant on the rippling waves doth look,
That peaceful still 'twixt bitterest foemen flow:
For proud each peasant as the noblest duke:
Well doth the Spanish hind the difference know
'Twixt him and Lusian slave, the lowest of the low.

XXXIV.

But ere the mingling bounds have far been passed,
Dark Guadiana rolls his power along
In sullen billows, murmuring and vast,
So noted ancient roundelays among.
Whilome upon his banks did legions throng
Of Moor and Knight, in mailed splendour drest;
Here ceased the swift their race, here sunk the strong;
