To Macklin's 'British Poets and Bible,' and to Bowyer's 'Hume's History of England,' he also contributed largely. 'The Death of Sapphira' is a remarkable example of his artistic power.
About this period he must have written the following letter to his sister, which is perhaps worth inserting—being, as it were, a peep behind the scenes, affording us a glimpse of his rough, affectionate nature:
'Nov. 20, 1800.
'Dear Bett,[121]
'What the devil is the reason that thou art in such a fright, indeed what should make thee suspect the contrary? My not having written is the very thing that ought to have kept thee quiet, for if any accident had happened to me thou certainly wouldst have heard of it by me and by many others, henceforth I desire thou wilt remember the old saying "no news is good news," and not fret thyself because I am lazy and don't like to write when I have nothing to say.
'My dearest Amelia was not so fortunate in coming to town as myself; she was overturned in the mail about 30 miles from town, and so bruised as to cause her to be lame for a fortnight or three weeks after, but she is now I hope perfectly recovered: she desires me to give her kindest love to you and mother, and to thank you for your presents.... Keep up Mother's spirits and tell her I am very well and hope to see her again next summer, and my wife hopes the same. Give my love to Mary James,[122] &c., &c., and believe me ever
'Affectionately yours,
'John Opie.
'Let brother's picture be sent off as soon as possible, and I will take care the other shall be sent down as soon as I have time to paint one of Amelia to go with it.'
But it is time to speak of his literary talents. Charles James Fox,[123] Horne Tooke, and Sir James Mackintosh had the highest opinion of his mental powers. Horne Tooke (whose portrait also Opie painted) says of him that he spoke in axioms worthy to be remembered; and Mackintosh observed: 'Had Mr. Opie turned his powers of mind to the study of philosophy, he would have been one of the first philosophers of the age. I was never more struck than with his original manner of thinking and expressing himself in conversation; had he written on the subject he would probably have thrown more light on the philosophy of his art than any man living.'
There is a capital short 'Life of Sir Joshua Reynolds' by Opie, written for Pilkington's 'Dictionary of Painters;' and the accompanying extract from a letter which he addressed to one of the periodicals on the subject of a grand national memorial to the triumphs of the British fleet, may serve as a specimen of his powerful, glowing style. Opie proposed a huge building in which everything connected with the subject might be displayed—including statues of our naval heroes, surrounded by pictorial representations of their achievements.
