Byron in “Don Juan” says:
All who joy would win must share it,
Happiness was born a twin.
(Speaking of the rare and exalted nature of Dorothea, who has adopted the normal, domestic married life) Her finely-touched spirit had still its fine issues, though they were not widely visible. Her full nature, like that river of which Cyrus broke the strength, spent itself in channels which had no great name on the earth. But the effect of her being on those around her was incalculably diffusive; for the growing good of the world is partly dependent on unhistoric acts; and that things are not so ill with you and me, as they might have been, is half owing to the number who lived faithfully a hidden life, and rest in unvisited tombs.
George Eliot (Middlemarch).
This passage, which finely expresses an important truth, is at the end of Middlemarch. The reference is to a story of Herodotus. He says that Cyrus, the Persian, was angry with the river Gyndes (Diyalah), because it had drowned one of the white horses, which, as being sacred to the sun, accompanied the expedition. He, therefore, employed his army to divert the river into 360 channels (representing the number of days in the year). The story was probably told to Herodotus as explaining the great irrigation system that existed in Mesopotamia. The Diyalah flows into the Tigris not far from Baghdad.
Any sort of meaning looks intense
