The following two verses express the poem théme:
"Be comforted; the world is very old,
And generations pass, as they have passed."
This poem is from Henry Wadsworth Longfellow (1807-1882), an American poet whose verses are still being recovered by young generations.
The poem theme is time as the factor which separates life and death. That´s why we can read in the first verses:
"if I were dead,
What would befall these children?".
A shadow is a dark area where light from a light source is blocked by an opaque object.
It occupies all of the three-dimensional volumes behind an object with light in front of it.
The cross-section of a shadow is a two-dimensional silhouette or a reverse projection of the object blocking the light.
