with less encouragement than his predecessor. _Mr. Jackson_,
however, has lately invented a new method of printing paper hangings
from blocks, which is very ornamental, and exceeds the common method
of paper-staining (as it is termed) by the delicacy of his drawings,
the novelty of his designs, and the masterly arrangement of his
principal figures.

The next notice appeared in the _London Evening Post_ of April 30-May 2,
1752:

New invented PAPER HANGINGS, printed in Oyl, which prevents the
fading or changing of the Colours; as also Landscapes printed in
Colours, by J. B. Jackson, Reviver of the Art of printing in Chiaro
Oscuro, are to be had at Dunbar's Warehouse in Aldermanbury, London;
or Mr. Gibson's, Bookseller, opposite the St. Alban's Tavern in
Charles-street near St. James's-Square, and no where else.

Several months afterwards, in the September 1752 issue of _Gentleman's
Magazine_, publication of the _Enquiry into the Origins of Printing in
Europe_ was announced.

The _Enquiry_ is an odd book. It combines rewritten versions of two
Jackson manuscripts, a study of the origins of printing in Europe and an
autobiographical journal covering, we suppose, the years from about 1725
on. The writer, in his introduction, says that he had been attracted by
the two notices mentioned and went to see Jackson, whom he already knew
by reputation. As a "Lover of Art" he considered it his duty to acquaint
the public with Jackson's ideas concerning the origins of printing.
These ideas, he felt, were an important contribution. After devoting
half the little book to a rambling account of this subject, including a
short history of woodcutting from Duerer onward, the author suddenly
shifts to the journal. It is regrettable that he condensed it because we
do not know what was left out. It is possible that much autobiographical
information was excluded, as well as a picture of woodcutters and
woodcutting of the time. The book concludes with the statement that
Jackson intended to print in October of that year (1752) a paper hanging
in two sheets after an original painting "by _F. Simonnetta_ of
_Parma_"[37] representing the battle fought near that city in 1738.

[Footnote 37: There is little doubt that Jackson meant Francesco
Simonini (1686-1753), a painter of battle subjects who was born in
Parma and lived in Venice in the 1740's.]
