House of M. Lucretius Fronto at Pompeii shows an enclosed flower-bed on cither side of a focal tree, reflecting the symmetry of the villa-facade
which overlooks it (plate facing p. 471). Little archaeological evidence of formal gardens is known, though one fine specimen has been reconstructed
in the villa at Fishbourne, with a central path bordered by hedges fashioned into a series of alternating rectangular and semicircular recesses. But that
such gardens existed on a grander scale in Rome and its surroundings is demonstrated by examples represented on the Severan marble plan of the city
(for example, in Vespasian's Temple of Peace) and by parts of a plaque now in Urbino preserving the plan of a funerary park.
Plan Of A Funerary Garden In Rome: engraving on marble (third or fourth century A.D.). The actual mausoleum, evidently a three-storeyed affair
with a square podium supporting a concave-sided structure crowned by a small rotunda, is shown at the bottom; behind it lies the garden, a formal
arrangement of lines of trees (indicated by small circles) and rectangular parterres.
