Sonnet 42
Spatial metaphor
Love measured as physical space—depth, breadth, height. She's making abstract emotion geometrically concrete, like surveying land or mapping territory.
Everyday vs. transcendent
Notice the shift: after cosmic soul-reaching, she pivots to ordinary domestic life. The same love operates at both scales simultaneously.
Political simile
"Men strive for Right"—1840s context matters. She's equating romantic love with abolitionism and reform movements. Love as political conviction.
Lost saints
She lost Catholic faith in her twenties. This love replaces religious devotion—the "lost saints" are literally the saints she stopped believing in.
