Recipes for varnish, glue and cloth-dyeing, with number rules
A dense miscellany: a riddle, painters' and dyers' recipes, and the arithmetic of Boethius and the parts of 60.
This crowded page gathers craft recipes and number lore. Among the recipes are lyes for washing brushes, a glue for working on cloth (with weighed doses of birdlime, turpentine, honey, sagapenum, soap and walnut oil), a clear juniper-and-walnut-oil varnish made without fire, and a long procedure for colouring woollen cloth by pouncing a design, stencilling with stamps, and fixing colours with aqua fortis, vinegar and kermes. A riddle at the top left ('I am he who was born before my father...') opens the sheet, while at the centre and right are two arithmetical schemes: the 'Rule of Boethius taken from Pythagoras' pairing numbers around 7, and a table of the aliquot parts of 60. A foliation mark 'A 190' stands at the top right.

Recipes for brushes, glue and juniper varnish
To wash brushes, use lye of oak-ash with quicklime and a little rock alum. A glue for working on cloth is compounded from weighed doses of white birdlime, turpentine, honey, sagapenum, white soap and walnut oil, dried in the sun into a paste. A clear varnish made without fire is drawn from gum bled from cut juniper, mixed with old, well-purified white walnut oil in a cup in the sun.
Colouring woollen cloth by pouncing and mordants
Cut stockings are stretched on a frame like an embroiderer's, the design is pounced and outlined in strong glue (better if applied with a carved wood stamp) so the colour will not run. Once dry, the pounced points are traced with aqua fortis; blues are made with strong vinegar, purples with boiled kermes-water over the blue, and yellows with aqua fortis, then the cloth is washed and soaked warm until the glue dissolves.
Rule of Boethius taken from Pythagoras
Take the first number above 7 (8) and the first below 7 (6): 8 and 6 make 14, whose half is 7. Continue pairing the greater with the lesser and the half is always 7: 9 and 5, 10 and 4, 11 and 3, 12 and 2, 13 and 1 all make 14, half 7.
The aliquot parts of 60
60 is broken into its parts: 1/60 is 1, 1/30 is 2, 1/20 is 3, 1/15 is 4, 1/12 is 5, 1/10 is 6, 1/6 is 10, 1/5 is 12, 1/4 is 15, 1/3 is 20, 1/2 is 30, 1/1 is 60. By this number a whole should be divided, and it will be useful.
Riddle: born before the father
A riddle opens the sheet: 'I am he who was born before my father, the third part of the men slain, then I returned into my mother's womb.'
