Metaphysicals

If we didn't know (from those portions vol. 2 of the Biographia that quote them) that Coleridge was reading Herbert and the metaphysicals, this strangulated, ineffective image from Zapolya (1816) would give the game away:

Be not ashamed that I should witness
The oil of gladness glittering on the water
Of an ebbing grief. [Zapolya (1816), 45]
