"The stitches used in modern embroidery are not productions of this age. They belong to the art of to-day through adaptation. They have a value because of their antiquity far above any value which new inventions in this line could possess. Their application has been tried without limit and the extent of expression and delineation through them is well know. The science of embroidery is established; its methods are perfected. The art is rich in its heritage."
L. Barton Wilson, Corticelli Home Needlework (1898)
I just discovered antiquepatternlibrary.org. This catalog of antique books and patterns (in pdf form) is extensive, with patterns from the 19th and early 20th centuries, and even a reprint of a German pattern book originally published in 1533.
There are so many ideas, patterns, and lessons on crochet, knitting, Irish crochet, tatting, embroidery and more, it's going to take quite a while to look through all of it. So far, Sherwood's Impression Powder and Perforated Patterns (1865) is my favorite.
