Song Meaning
The speaker is making a resolute departure from the Tagus river, signaling a farewell to Spain. This isn't a casual goodbye; it's a purposeful journey towards the Thames in England. The tone is one of determined ambition and unwavering loyalty.
The core tension in these lines emerges from the contrast between the two rivers. The Tagus is associated with "grains of gold already tried," suggesting past endeavors or resources that are now known or perhaps exhausted. In contrast, the Thames is approached "Gainward the sun," implying a move towards new opportunity, prosperity, and a future of "wealthy pride."
The craft here is particularly effective in how it elevates the destination. The English town is not just a place but one "which Brutus sought by dreams," lending it a mythical, fabled quality. Further, it's described as a "bended moon doth lend her lusty side," an intriguing image that blends the allure of the moon with a sense of vibrant, fertile abundance, making the destination deeply appealing.
Ultimately, these lyrics hit hard because they ground this grand, purposeful voyage in an absolute declaration of devotion. The speaker states, "My king, my country, alone for whome I live," making the journey an act of profound duty. The idea that "mighty love the wings for this me give" transforms a physical crossing into a powerful, almost spiritual flight, driven by an all-encompassing commitment.
