On this matter it is interesting to read the following piece¹.
It is instructive to consider some of the words that we derive from
Arabic, such as: algebra, alcohol, alchemy, alembic, alkali,
azimuth, zenith. With the exception of "alcohol"—which meant, not a drink, but a substance used in chemistry—these
words would give a good picture of some of the things we owe to the
Arabs. Algebra had been invented by the Alexandrian Greeks, but was
carried further by the Mohammedans. "Alchemy,” "alembic," "alkali" are
words connected with the attempt to turn base metals into gold, which
the Arabs took over from the Greeks, and in pursuit of which they
appealed to Greek philosophy. "Azimuth" and "zenith" are astronomical
terms, chiefly useful to the Arabs in connection with astrology.
The etymological method conceals what we owe to the Arabs as regards
knowledge of Greek philosophy, because, when it was again studied in
Europe, the technical terms required were taken from Greek or Latin.
In philosophy, the Arabs were better as commentators than as original
Their importance, for us, is that they, and not the Christians, were
the immediate inheritors of those parts of the Greek tradition which
only the Eastern Empire had kept alive. Contact with the Mohammedans,
in Spain, and to a lesser extent in Sicily, made the West aware of
Aristotle; also of Arabic numerals, algebra, and chemistry. It was
this contact that began the revival of learning in the eleventh
century, leading to the Scholastic philosophy. It was later, from the
thirteenth century onward, that the study of Greek enabled men to go
direct to the works of Plato and Aristotle and other Greek writers of
antiquity. But if the Arabs had not preserved the tradition, the men
of the Renaissance might not have suspected how much was to be gained
by the revival of classical learning.
