Analysis of In The Garden II: Visions

HERE I am slave of visions. When noon heat
Strikes the red walls, and their environ'd air
Lies steep'd in sun; when not a creature dare
Affront the fervour, from my dim retreat
Where woof of leaves embowers a beechen seat,
With chin on palm, and wide-set eyes I stare,
Beyond the liquid quiver and the glare,
Upon fair shapes that move on silent feet.
Those Three strait-robed, and speechless as they pass,
Come often, touch the lute, nor heed me more
Than birds or shadows heed; that naked child
Is dove-like Psyche slumbering in deep grass;
Sleep, sleep,--he heeds thee not, yon Sylvan wild
Munching the russet apple to its core.
