8 Cultural patterning in Islamdom and the Occident 129
nature of this dominance has been misunderstood. The peculiar notion
of some modern Western writers, that before the sixteenth century other
societies, such as the Islamicate, were "isolated" and were brought into
the "mainstream" of history only by such events as the Portuguese inva-
sion of the Indian Ocean, is of course ridiculous: if there was a "main-
stream," it was the Portuguese who were coming into it, not the Mus-
lims;
the Muslims were already there. But the contrary notion, also
found among Western writers, that in the High Caliphal Period Arab or
Islamicate culture was the greatest in the world, that Cordova or Bagh-
dad were incomparable centers of wealth and learning, is almost as
poorly founded. It springs equally from the unconsidered assumption
that the Occident was the "mainstream" of world history and culture.
Compared with the Occident, in the High Caliphal Period, when the
Occident was still rather a backwater, Islamdom looks magnificent; but
such a comparison says nothing about its relative position in the world;
the Baghdad of the caliphs was merely on a plane of relative equality
with Constantinople in eastern Europe and with the metropolises of
India or China. (In the Earlier Middle Period, when the Occident was
more developed, Islamdom looks less strikingly glorious in comparison;
but most of the change in appearances is due to a change in the level of
the Occident, not in that of Islamdom.) The well-known cultural superi-
ority of Islamdom, then, was not absolute in the world at large (in the
Earlier Middle Period, surely it was in China, if anywhere, that would be
found the maximum economic and cultural prosperity); it was relative to
the developing Occident.
Yet in certain respects, Islamdom was indeed pre-eminent in the
Oikoumene. For the configuration of regional lettered traditions in the
Oikoumene had, in the course of the other changes, itself subtly
changed. In the Axial Age three great lettered traditions had been
launched in the Indo-Mediterranean zone, the Sanskritic, the Irano-
Semitic, and the Hellenic, in relatively close relations with each other but
in rather tenuous relations with the fourth lettered tradition, the Chi-
nese.
The same four traditions still formed the matrix of all high culture;
but their pattern had been altered now in three ways. First, the Irano-
Semitic traditions had loomed much larger under Islam. In the early
post-Axial centuries, the Irano-Semitic lettered traditions seemed almost
ready to be submerged under waves of Hellenization and even of
Indicization. By late Sasanian times, these traditions were asserting full
autonomy, and under Islam the Irano-Semitic heritage was clearly estab-
lished on an equal level with the others - or more than an equal level;
for by 1300 already the other two heritages were being submerged, at
