The speaker addresses a beloved friend, telling him how often he’s called on him for inspiration—and how well it has worked. Other writers, seeing this, have started using him as a muse too: their verses, the speaker says, are now scattered “under thee.” The beloved’s eyes have a miraculous power, teaching the silent to sing and lifting ignorance high into the air. Even genuine scholars gain fresh brilliance from him. But the speaker draws a sharp line. In those other poets’ work, the beloved merely refines a style or adds a decorative sweetness. For the speaker, the beloved is everything—the sole source of his art. He doesn’t just polish rough edges; he transforms the speaker’s “rude ignorance” into something that rivals learning itself. The feeling is intimate and quietly possessive, a proud tenderness that leans wholly on one person.
Sonnet 78: So oft have I invoked thee for my Muse — Summary
So oft have I invoked thee for my Muse, And found such fair assistance in my verse As every alien pen hath got my use And under thee their poesy disperse. Thine eyes, that taught the dumb on high to sing And heavy ignorance aloft to fly, Have added feathers to the learned's wing And given grace a double majesty. Yet be most proud of that which I compile, Whose influence is thine, and born of thee: In others' works thou dost but mend the style, And arts with thy sweet graces graced be; But thou art all my art, and dost advance As high as learning, my rude ignorance.
