Here is a bit more information about the objects in the scene, and some of
the techniques I employed in creating them. This may provide more detail
than anyone would ever want to read, but better too much than too little.
In the foreground, moving from front to back, are:
-
Some calligraphy. The text is copied out of a book entitled A Treatise
Of Daunses, wherin it is shewed, that they are as it were accessories
and dependants (or thinges annexed) to whoredome : where also by the way
is touched and proued, that Playes are ioyned and knit togeather in a
rancke or rowe with them, printed in 1581 by an anonymous author
(though I assume he was a Calvinist minister, as they tended to denounce
in print anything even the least bit fun, but especially dancing and the
theatre, and it was published about the time many other Calvinist
ministers, such as John Northbrooke, were printing similar things). The
calligraphy style is an English secretary hand, given in Richard
Field's 1611 book of penmanship, and was the most prevalent style of
handwriting during that period. The scanned image is mapped onto a
bicubic patch.
-
A quill pen. These were usually made from the feathers of a goose's
wing (preferably the second or third feathers, or, failing that, the
pinion feather), or a raven's. After being prepared (which involved
soaking in water for 24 hours, then being "tempered" by being plunged
first into a bucket of sand soaked with boiling water, then into cold
water), the barbs were stripped off, the quill shortened to a manageable
length, and finally the nib was cut with a pen-knife and a cleft made
to carry the ink to the tip. The cardioid cross-section of the pen was
modelled using the formula r=a(1-cosA), and projected along the Z axis
with a shallow curve in the -X direction, and a shallower curve in +Y,
to model a feather taken from the right wing of a goose. This was all
accomplished as a mesh calculated with nested #while loops.
-
Scratch paper. The Rules by F.B. for Children to write by, contained
in Field's book, mentions keeping "brown paper for great hast, or else
boxe with sand". While it was used primarily for soaking up blots and
spills, scratch paper is also handy for getting past the heavy flow of
ink after one has just dipped the pen. This was also a scanned image
put onto a bicubic patch, but by the time I moved it around to where I
was happy with it, the turned-up corner had moved off the image.
-
A stick of sealing-wax. Unlike beeswax or candle wax, sealing wax is an
incredibly hard substance. Period sources stipulate that it should be hard
enough to require that it be broken in order to open the paper beneath
it, but sturdy enough that it not shatter immediately. Period recipes
indicate a mixture of shellac, turpentine and rosin, which results in
a rather shiny substance that bears a surprising resemblance to plastic.
-
A bottle of ink and its cork. I originally designed this as a lathe
object, but that slowed down the rendering to such a staggering degree
that I remodelled it as a CSG object. This wasn't much better, but at
least it showed some improvement in speed. The cork texture is based
on the one in the standard POV-Ray include files, but modified to give
darker bits.
-
A pen-knife. Used for cutting the quill, pen-knives had a short blade
with a curved cutting edge. In order to get rounded edges, the wooden
handle is a CSG composed of bits sliced out of superellipsoids.
-
A candlestick. Loosely modelled on a brass candlestick I had floating
about my apartment, it comprises two lathe objects, two meshes and a
couple of primitives. In retrospect, the bottom mesh object (the
hexagonal base) could have been more easily constructed using a prism
with a conic sweep, but since I did that one in the wee hours of the
morning, my thought processes were a bit fuzzy. I had wanted to give
slightly rounded edges to the mesh object that makes up the majority
of the candlestick's height, but couldn't quite get the hang of smooth
triangles.
-
A candle. The first object I created for this scene. I wanted to model
the fact that wax or tallow candles seem to glow at the top from the
light coming from the flame. Unfortunately, the only method that really
seemed to work made the wax appear to be brighter than the flame itself,
but overall I think the effect isn't too bad.
-
A piece of bread. Because they didn't have rubber erasers, students
learning to write would erase their ruling lines with bread, squooshed
up the way all children seem to do instinctively when playing with
bread. It doesn't work too badly when using actual lead, as long as
the marks are lightly made (the results are rather disappointing when
trying to erase modern graphite pencil marks, but it does work to some
degree). Because period "white" bread was only about as white as modern
wheat bread, I made the interior a little tan. Its inner surface is a
combination of a bumps normal and a CSG difference of lots of
little spheres.
-
Books. Unfortunately, I didn't have any books from the time period I
was portraying, so I used the oldest books I possess as models. They
are admittedly anachronistic, but I hope that this inaccuracy may be
forgiven me in light of the fact that binding techniques changed little
between the 17th and 19th centuries. As the greatest amount of time was
spent on these books, specific comments on their construction and
histories may be found in each book's include file; the Roxburghe
Ballads are in book1.inc and book2.inc, the book in the centre is in
book3.inc, and the thick, badly damaged book is in book4.inc.
The room in the background is loosely based on the drawing-room of Edmund
Blackadder (from the British historical sitcom Black Adder II). Because
the room was intended to be very dimly lit, I did not spend an inordinate
amount of time on fine details. At first, I was worried that the shadows
of the candles on the far wall were unrealistic, but experimentation with
real candles convinced me that my fears were unfounded. The portraits on
the walls are of myself (centre) and two of my friends in Elizabethan
clothing, and the Tudor-style house visible through the window is based upon
a building in Winchester, England (near a structure known as "The Cross").
Items that I had originally wished to put into the picture were a pile of
"Stanch graines", used for preparing the writing surface, and black lead for
ruling lines on the paper. However, I omitted them for the sole reason that
I didn't know what they looked like. For example, I feel fairly sure that
one wouldn't use a plain old hunk of lead, but was there some sort of stylus
used with it, like a modern pencil or a silverpoint stylus, or was it just
formed into a stick, as is done with modern artists' charcoal?
The "Rules by F.B. for Children to Write by", upon which I based this image,
was taken from the book entitled, A NEVV BOOKE, Containing all Sorts of
Hands vsvally written at this Day in Christendome, as the English and French
Secretary, the Roman, Italian, French, Spanish, high and low Dutch, Court
and Chancerie hands:with Examples of each of them in their proper tongue and
Letter, imprinted at London by Richard Field, 1611. The Rules are
available on the Web at

for those who are interested in such things.
