"O what can words, / The weak interpreters of mortal thoughts, / Or what can thoughts (tho' wild of wing they rove / Thro' the vast concave of th'aetherial round) / If to the Heav'n of Heavens they'd win their way / Advent'rous, like the birds of night they're lost, / And delug'd in the flood of dazzling day."
— Smart, Christopher (1722-1771)
Exists from everlasting, whose great Name
Deep in the human heart, and every atom,
The Air, the Earth or azure Main contains,
In undecypher'd characters is wrote--
INCOMPREHENSIBLE -- O what can words,
The weak interpreters of mortal thoughts,
Or what can thoughts (tho' wild of wing they rove
Thro' the vast concave of th'aetherial round)
If to the Heav'n of Heavens they'd win their way
Advent'rous, like the birds of night they're lost,
And delug'd in the flood of dazzling day.--
(p. 17, ll. 1-12)
