Find 2 examples of metaphor in the poem below
In this kingdom
the sun never sets;
under the pale oval
of the sky
there seems no way in
or out,
and though there is a sea here
there is no tide.
For the egg itself
is a moon
glowing faintly
in the galaxy of the barn,
safe but for the spoon's
ominous thunder,
the first delicate crack
of lightning.
