In the early part of the eighth century, Islam, at first represented by Berbers and later by Saracens, occupied roughly what had once been Carthaginian Spain, only temporarily holding the north-western quadrant which became a centre of Christian resistance; it had previously remained, for a time at least, apart from the Wisigothic kingdom. The hold of Islam on the east coast north of Tarragona was also only temporary, but as a result of this the Barcelona region during the formative period of language was more in touch with South France than with the north-western and Christian part of Spain, whence its language came to have the kinship with the _langue d'oc_ already noted. In the centuries of Iberian weakness in face of Islam the west coastal plain diverged in speech from the upper Douro basin. As Islam weakened in Spain the west coast language spread southward, while the plateau language (Spanish) spread south especially via Toledo, the Guadiana region being largely waste land for the time. As Spanish, the language of the defenders of Christianity, became the replacer of Islamic languages, it, rather than Catalan, spread over the parts of the east coast south of the Ebro as they were recovered for Christianity. When the north-west was the basis of resistance to Islam, the age-long sanctity of Compostella came into prominence, and the great shrine of St. James (Santiago da Compostella) became world famous, and later on, a centre of pilgrimages. Thus in spite of the kinship of Galician with Portuguese, Galicia became part of the kingdom of Spain, though its seafarers had much in common with the coast-dwellers of northern Portugal. One should note also that, whereas in Portugal the coastal plain has the severe barrier of the plateau edge to divide it from Spain, in Galicia the lines of hill spurs grade down to the sunken coast-line without any marked change. Though Berber and Saracen elements have been suppressed, {32} a good deal remains to attest their influence not only in cities and their buildings but in the cultivation of the south, and especially in the irrigated gardens (_buertas_) of the east coast and in many features of the people's life, even in some details of dialect. Arabic is now studied a good deal as a 'classical' language in these regions.
