deviation from perfect circularity is clear.

carving. Bottom: details of the staff pattern
The style of the ornaments allows an inference for the
construction date of the original monument to be made. Their
detailed, fully 3D inclusion into the model (e.g. figs. 11 and 12)
is therefore not without importance, also for the scholar. At
Sagalassos, the closest parallels for the decoration of the
nymphaeum can be found in the cornices of the NW shrine,
dated to the middle of the second century AD. The motifs on
the nymphaeum however have often evolved slightly
further. On the one hand, the decoration on some blocks is very
plainly executed, an evolution which had begun on the NW
shrine (Vandeput, 1997b). On the other hand, the finely dented
Acanthus is widespread, and the acanthus, the floridly-carved
palmettes and the scrolls are executed following exactly the
same method so that the distinction between these motifs is
diminishing.
Motifs such as the scroll and the acanthus are more
disconnected than corresponding decoration on monuments
from around the middle of the century. Both decoration motifs
now appear to be built up of several independent parts, a
characteristic, which returns on monuments from the second
half of the second century AD elsewhere. The lack of natural
qualities in the scroll, for example, and the very plain treatment
of motifs on the blocks of the nymphaeum, together with the
extreme relief of the rosettes on the pilasters and in the coffers,
all clearly designed to produce strong patterns of light and
shade, seem to indicate a later date than the middle
of the second century. The best parallels for acanthus and
Corinthian capitals, for example, occur on monuments such as
the Faustina Baths at Miletos (AD 160-170) and the Agora
Halls at Smyrna, restored after AD 178. Motifs with strongly
serrated outlines also seem to occur especially from the
Antonine period onward. Some motifs on the nymphaeum, such
as the leaf bands on the soffits, even seem to presage Severan
decoration. Taken all together, a date in the middle Antonine
period (AD 160-180) seems most probable (Vandeput, 1997a).
The building on the whole represents the culmination of a
tendency towards polychrome architecture at Sagalassos, with
the Temple for Hadrian and Antoninus Pius as a precursor, with
its combination of 2 colors. (Waelkens, 2003) Hence, fidelity of
the textures in the model is crucial.
4. CONCLUSIONS
In this paper, we have tried to build a case for photo-realistic
and detailed 3D modeling. On the one hand, cost-effective
technologies are becoming available to make such approach
affordable at a larger scale. On the other hand, such models
offer a richer experience for the public, and in fact also
for the scholar. We have presented a 3D model of the Antonine
nymphaeum at Sagalassos as a case in point.
Of course, the creation of such a model still represents a
substantial effort. One of the goals of the European Network of
Excellence EPOCH (Excellence in Processing Open Cultural
Heritage (Epoch, 2004)) is to help streamline the process, in
order to further reduce the necessary efforts and to ensure
compatibility between and easier access to different
technological modules.
