According
to A.M. Clevely in his excellent book "Topiary: The Art of Clipping
Trees and Ornamental Hedges" (Collins) published in 1988 "the
definitive history of topiary has yet to be written."
This is in book form let alone on the
Internet but I'll try to give you a quick run through here.
Although the Seventeenth Century is seen
as the Golden Age of topiary clipped trees and bushes can be traced
back to the Egyptians and the Ancient Romans. See the section on the
Roman Consul Pliny the Elder on the Home Page.
Although gardening was popular amongst the upper classes the actual
physical work was done by the slaves in many cases. The one who looked
after the ornamental garden (the Topia) was thus known as the Topiarus.
Many writers think that Egyptian, Syrian Greek or Jewish slaves were
the first people to introduce the art to the Romans.
The Persian Empire was also known to
have splendid hedges with clipped Myrtle and the ancient Egyptian garden
often showed a formal symmetry as can be seen from the many surviving
paintings.
After the fall of the Roman Empire in
Italy the monks kept the art of topiary alive in the cloisters of their
monasteries. In the Renaissance the wealthy families who were often
as devout as they were ruthless paid to have elaborate gardens in their
villas based on the learning of these monks who took their inspiration
from the writings of the Ancients. The poet Petrarch, amongst others,
emulated Virgil in writing about formal landscapes for instance.
In 1467 a monk called Francesco Colonna
published a book called "Hypnerotomachia" which was an allegorical
work set in visionary gardens and this had a profound influence on subsequent
Italian aristocracy and their gardens.
By 1520 Renaissance ideas had spread
to France who were particularly taken by the use of hedges to give formal
structure. This culminated in the Work of Andre le Notre with his massive
designs for formal hedging for King Louis the Fourteenth at the Palace
of Versailles just outside Paris. The Versailles style spread across
Europe to great gardens in Denmark, Germany, Russia and Sweden. The
Dutch however were to emphasise the figurative aspects of the Versailles
style and this was one which Britain, with its links to that part of
the world took on enthusiastically. The use of individual specimens
in the Dutch manner can be particularly seen at Levens
Hall in Cumbria.

Mazes and labyrinths were popular in
Britain from after the Norman Conquest but it was in the Seventeenth
Century that topiary became part of the formal landscape. As with all
fashions, however, this was to be fairly short-lived as the mania for
the Landscape style, made popular by such exponents as
Lancelot "Capability" Brown meant that many formal topiary
gardens were ripped up in the pursuit of open parkland. Fortunately
it never entirely died and small cottage gardens continued the art as
the British are especially noted for their eccentricities.
Another revival came in the 1830's when
such gardens as "Mon Plaisir" in the grounds of Elvaston Caste
in Derbyshire were laid out as by now many people had begun to tire
of landscape expanses. The Victorians developed topiary, as they did
all other aspects of garden design and machinery and of course it continued
to thrive in the Twentieth Century with the efforts of Major Lawrence
Johnston at Hidcote Manor in Gloucestershire,
Vita Sackville West at Sissinghurst
Castle in Kent and many others.
Today topiary is thriving, in some small
part due to the "Topiary in the United Kingdom" website
and the nurseries you can find on our Where to Buy
