lighter it is, the better it is purified. There are some persons who
bury it when they have thus purified it, and so keep it many years
before they use it; and others do the same in the open air upon the
roof. There are also some persons who add half the quantity of mar-
ble dust, which they first pound very fine. It has also been observed,
that if the white pigment be put in the open air, in a large vase, and
boiled water be thrown into it, at the same time mixing it with a
stick, the next day putting it in the sun, it will be sufficiently purified,
and may be used the following day for mixtures with other colours,
but not for colouring naked bodies.
Of preserving the colours.—Having now prepared and ar-
ranged the colours in the manner above-mentioned, and put them in
their vases, in order to preserve them uninjured, we must next take
shells or small vases, and begin to mix the tints. First put some
white into three or four of these shells, and then put some black in
just the same number of others, but not in such great quantity; then
take the vase of pure colour, either yellow, red, blue, green, or
whatever other colour is wanted, pouring it in, and mixing it
with this white, which has been put into these shells or vases, so as
to make at least three tints, one lighter than the other, by putting
less of the pure colour into some than into others. The same colour
must also be poured in a similar manner into the shells where the
black, or any other dark colour is placed, observing the above direc-
tions as to making them one darker than another ; so that, by these
means, from each pure colour, may be obtained four or six shades,
and as many tints as may be wished, and these must correspond with
the colours ia the design or well finished cartoon. But with regard
to the minute differences of the colours which nature presents to us,
we shall not enter into any farther description of them, as their num-
ber is infinite, which is rendered evident at once by considering the
continual variation of colour in fruits and flowers; and if we would
imitate these colours, we must make a tint resembling the colour of
each.
Of the mixture and application of colours.—But of all the
usual mixtures for flesh, the lighter ones are always made of red
earth (Terra Rossa) and white, and that they are made more or less
dark in the same manner as other tints; but these are not always
the same, because, as regard must be had to the variation of the
