I have been making a hankie for my niece. It is from "Guipure-und Cluny-Spritzen" which you can get with translation (for us German-challenged types) from the NELG library if you don't own a copy. This is Genoa lace, although done on a finer pricking than recommended with 50/2 EC. The pattern is said to date from about 1610.
What amazes me is that there is a Velazquez portrait at the Metropolitan Museum of Art of Juan de Pareja who was Velazquez's "Moorish slave". This is a beautiful portrait. Juan has a lace collar that is not painted in great detail, but from what I can make of it, the lace that I am making could be very similar, at least in style. Here is a link to the Wikipedia entry where there is a fairly good picture of it: http://en.wikipedia.org/wiki/Portrait_of_Juan_de_Pareja
