Leichte Künsteleien zum Vergnügen und zum Nutzen für Kinder und Nichtkinder by Dr Heinrich Rockstroh, 1819 | |||||||
'Leichte
Künsteleien zum Vergnügen und zum Nutzen für Kinder
und Nichtkinder' by Dr Heinrich Rockstroh was published
by Ludwig Wilhelm Wittich in Berlin in 1819. I learned
about this work from Edwin Corrie. The Frontispiece (see Selected Pages below) shows a woman who appears to be making a cut in a piece of folded paper. This design is not referenced in the book. A copy of the work can be accessed online here. A translation into Dutch was published as 'Magazijn van belangrijke en leerzame kunststukjes, voor jonge lieden' in 1828. Various sites which refer to this Dutch title say that it was translated, not from the 1819 book, but from the 'Journal für Kunst und Kunstsachen, Künsteleien und Mode' of 1911, which Rockstroh edited. I have not been able to access a copy of the journal to confirm this information. ********** Analysis Das Neckende Schloschen / Die behangte herigeftalt - a version of the Cherries Puzzle. ********** Das richtig beschnittene Briefblatt (The properly trimmed letterhead) (This is a method of creating a perfect rectangle, by folding, pricking and cutting, from an unevenly edged sheet of paper.) ********** Der kleine lichtfegel (The little light) ********** Die sonderbare Klappe (The strange flap) - The Chinese Wallet ********** Die elliptische Rundung (The elliptical curve) p11 (How to cut out an ellipse from a doubly folded sheet of paper) ********** Das verfangliche Laschchen (The insidious flap) p13 - The Puzzle Purse ********** The Square Letterfold ********** Der geficherte Zuschluss (The secure connection) This is a description of how to fold a letter that is more secure, and able to be more securely sealed with wax, than a standard folded letter. ********** Der Winkler aus Papier (The paper angle) How to fold a right angle from a sheet of paper. ********** Das erkunftelete Quadrat (The obtained Square) How to draw a square using 'Der Winkler aus Papier' ********** Selected Pages ********** |
