Book 1, lines 17-23 of the 1667 version...
And chiefly Thou O Spirit, that dost prefer
Before all Temples th' upright heart and pure,
Instruct me, for Thou know'st; Thou from the first
Wast present, and with mighty wings outspread
Dove-like satst brooding on the vast Abyss
And mad'st it pregnant: What in me is dark
Illumine, what is low raise and support;
I am humbled to be asked to join your team, Elaine Erig.
I will not post often; this is your blog.
And I will contribute.
Thank you very much.
I am honoured.
