The Book of Old Sundials & Their Mottoes (1922) is uncredited although it contains an introductory essay which may be the work of the Viscount Knutsford. The mottos section runs throughout the rest of the book, a collection of philosophical rhymes, moralising admonitions and the inevitable sombre memento mori. The illustrations by one Warrington Hogg are an equal attraction, showing the variety of sundial construction with examples from buildings in England that date back to the Roman occupation. Hogg’s drawings themselves date from the 1890s so its possible this is a reprint of an older volume. See the rest of the book here or download it here.
