Famous quotes containing the words fish and/or scales:
“The laying of fish on the embers,
the taste of the fish,
the feel of the texture of bread,
the round and the half-loaf,
the grain of a petal,
the rain-bow and the rain.”
—Hilda Doolittle (1886–1961)
“For these have governed in our lives,
And see how men have warred.
The Cross, the Crown, the Scales may all
As well have been the Sword.”
—Robert Frost (1874–1963)
