The Arabs, their cycle of conquest over, assimilated the Greek learning flourishing in Persia, and in their turn became the representatives, guardians, and teachers of ancient knowledge. Civilisation, or what was of great value in the Greek world, was not dead; it had gyrated; and the Arabs, having received science from the ancients, gave to every branch of it an accuracy and enlargement at once unforeseen and substantial. The following sketch will enable us to see that their triumphs in philosophy, mathematics, astronomy, chemistry, and medicine were both glorious and durable. In order, however, fully to understand the part which the Arabs have played in the progress of mankind, it is necessary to see what sort of civilisation theirs was?and this necessitates a short description.
