Who Has Seen the Wind? by Christina Rossetti, 1830 - 1894

Christina Rossetti in 1866 by Dante Gabriel Rossetti

Who has seen the wind? 
Neither I nor you. 
But when the leaves hang trembling, 
The wind is passing through. 
Who has seen the wind? 
Neither you nor I. 
But when the trees bow down their heads, 
The wind is passing by.

"On December 5, 1830, Christina Rossetti was born in London, one of four children of Italian parents. Her father was the poet Gabriele Rossetti; her brother Dante Gabriel Rossetti also became a poet and a painter. Rossetti’s first poems were written in 1842 and printed in the private press of her grandfather."
