Sundial plates : Scientific Instruments
Our handmade scientific
instrument sundial plates are
accurate for the UK mainland
and can be adapted for overseas
These are scientific instruments
and should not be confused with
purely ornamental sundials.
We have examples of each in

rose, the equation of time and the motto
“Thus Life, whilst it flies, seems to stand still”inscribed in Latin text.

Century. There is ample space below the gnomon for
a personal message or motto, included in the price.

Diameter 26.5cm (10½ ins)
Some points to consider
when choosing a sundial:
A circular sundial plate will work
well on a square or round top,
or on a capital.
A square plate or hexagonal
plate works best with a square
Always site your sundial away
from shade, sun is its raison
The gnomon or arrow must
point due north towards Polaris,
the North Star.
To be accurate, the plate must
be completely horizontal.
Scientific sundials often have
the ‘equation of time’ engraved
on them, for use in the accurate
telling of time.
To set up a Chilstone sundial,
you will need a firm, horizontal
base, a compass, a non-shady
location and a sunny day.

works very well with the large Bedford, or large
Penshurst, sundial plinths. A personal message or
motto is included within the price.
