A dazzling vapor of light

From The End of the Tether by Joseph Conrad. Love this opening paragraph. It has been years since I sailed but this evokes strong memories.

For a long time after the course of the steamer Sofala had been altered for the land, the low swampy coast had retained its appearance of a mere smudge of darkness beyond a belt of glitter. The sunrays seemed to fall violently upon the calm sea—seemed to shatter themselves upon an adamantine surface into sparkling dust, into a dazzling vapor of light that blinded the eye and wearied the brain with its unsteady brightness.
