Isaac Johnson

The artist was a surveyor and antiquarian as well as an artist who lived in Woodbridge, Suffolk for his adult life. Around 1785 he was considering a volume illustrating the most remarkable trees of Norfolk and Suffolk which never came to fruition, but for which the current drawing would have been a likely candidate.

White's History, Gazetteer, and Directory of Norfolk, 1883 describes the tree which stood on the estate of the Earl of Albermarle:

The celebrated 'Winfarthing Oak,' probably the largest in England except the one at Cowthorpe, in Yorkshire, stands near the Lodge farmhouse, and is a grand and picturesque old ruin. It measures 70 feet round at the roots, and 40 feet in the middle of the main stem, and must have been at one time a magnificent spreading tree, with enormous arms. It is traditionally said to have been called the 'Old Oak' in the time of the Conqueror, and is usually considered to be more than 1200 years old. It is now a mere shell, bleached snowy white, and capable of containing a large number of persons in its interior. It still retains vitality on its south side, and three years ago a rook's nest was built in its branches.
