Elettricismo atmosferico lettere
An 18th-century Italian treatise on atmospheric electricity by Giambatista Beccaria (1716-1781), printed in 1758 at Colle Ameno in Bologna by the press All'Insegna dell'Iride, written as letters for a learned readership. Its pictures are printer's ornaments: black woodcut vignettes of baroque scrollwork, garlands, a face mask, and a bundle of books with musical and scientific instruments, useful for decorative borders, headpieces and cartouches.
