ALL CREATURES GREAT & SMALL
Our clinic name is derived from, and credited to, a book series and television show by English author James Herriot.

In turn, Mr. Herriot appears to have been inspired by a hymn for little children, credited to Mrs. Cecil Frances Humphreys Alexander, published in 1848.  The following is the chorus of the hymn:
All things bright and beautiful,
All creatures great and small,
All things wise and wonderful:
The Lord God made them all.

In turn, it appears Mrs. Alexander was inspired by the epic poem of English poet Samuel Taylor Coleridge, “The Rime of the Ancient Mariner” which was first published in 1798.  The morale of the story of course is the Mariner being forced to wander the earth for eternity, telling his tale as penance for killing the albatross.  As part of this moral, it is noted in great poetic form:
He prayeth best, who loveth best
All things both great and small;
For the dear God who loveth us,
He made and loveth all.
