Sun Studies
Use the sundial for your appropriate latitude
closest to that of the site (Montréal is
45 degrees). The model must be to
scale and show anything that will cast a shadow.
Mount a copy of the sundial on the model
(horizontal surface) of the site with north on the
sundial corresponding to north on the
model. This sundial is designed to work for both
north and south latitudes. In this
case, it is printed with north as up for the Northern
Hemisphere. Mount the peg of the
size indicated at the cross marker. By tilting the
model in the sun, one can make the end
of the peg's shadow fall on any intersection of
the sundial. Only the real sun will
work; desk lamps do not have parallel rays, and thus
will give splayed shadows. Each
intersection represents the time of day and the day of
the year corresponding to the two lines
that meet at that intersection. When the shadow
extends to a given intersection, the shadows
and sun penetration in the model simulate
the actual condition for that time of
day and date. (Lynch, 1971, p. 71)
