The Book of ceremonial Magic

The instruction continues---As it is sometimes necessary to write with coloured inks,
have several horns containing white inks, in which infuse thy colours for the pentacles
and characters. The colours must be diluted with the blessed water which we term
exorcised, and with gum arabic. Lastly, perfume them. Let this be done with all devotion,
humility and

faith, wanting which nothing can be accomplished, says the Grimoire.
The same work gives particulars concerning the extraction of the sword-feather from the
right wing of a swallow, preceding the action with the words Yin He. It should then be
made into a pen by means of the Knife of the Art, and the name Anereton must be written
on it with the goose-quill, after which the Psalms Ecce quam bonum et quam jucundum
and Laudate Dominum ommes gentes 1 are to be recited over it, followed by aspersion
and fumigation.
It is not to be supposed that any ordinary ink could be suitable for so serious a business as
that of engrossing pacts. Even the consecrations previously given are inadequate in such a
case. It is understood that the signature is written with the blood of the operator, but the
deed itself requires a special preparation, as follows:--Place river-water in a new,
varnished earthenware pot, together with the powder hereinafter described. Then take
sprigs of fern gathered on the Eve of St. John and vine twigs cut in the full moon of
March. Kindle this wood. by means of virgin paper, and when the water boils the ink will
be made. It must be changed each time that there is occasion to write, that is to say,
whensoever the appellation of a spirit is undertaken.
Powder for Pact-Ink
Gall-nuts 10 Oz.
Roman Vitriol or Green Copperas
Rock Alum or Gum Arabic
3 Oz.
3 Oz.
Make an impalpable powder, and when you would compose the ink, use as above
described.
The authorities for this process are not the Grimoires proper
p. 168
but the collections of Magical Secrets which are sometimes appended to them but
sometimes form independent works.
