"Thou art weighed in the balances, and art found wanting" (BM J,4.119)

Watson, Bishop of Llandaff (left), and Gibbon (right) sit on the opposite scales of a balance, with their respective works, Gibbon outweighing Watson. Watson, wearing a mitre and lawn sleeves, sits on a pile of six volumes inscribed 'Theological Trac[ts]', saying, "Boy - Put in the Chymical Essays". A ragged boy kneels below the scale holding up to the bishop a pamphlet inscribed 'An Apology for Christianity In a Le[tter]'. Beside him is a pile of five books, one inscribed 'Chymical Essays by ... '. Gibbon sits complacently on volumes '1' to '3' of 'Gibbons Roman history'. Volumes '4-6' are piled up beside him. June 1788 [So dated by Miss Banks]
