granted to it on the still free arena of the intellectual world the only possible compensation, and that, too, a glorious one. For us the local circumstances are above all to be taken into account. Artificial gardens are in some measure independent of the soil, and it is not otherwise with these scientific institutions; only that they from their nature are directed towards the courts. Material support may be imparted to them otherwise; but more important than this is the favour of the highest circles, which swells their sails, and the connections, which, meeting together in the great centres, replenish and extend these circles of science. In the better time of the monarchies of Alexander there were as many such centres as there were states, and that of the Lagid court was only the most highly-esteemed among them. The Roman republic had brought the others one after another into its power, and had set aside with the courts also the scientific institutes and circles belonging to them. The fact that the future Augustus, when he did away with the last of these courts, allowed the learned institutes connected with it to subsist, is a genuine, and not the worst, indication of the changed times. The more energetic and higher Philhellenism of the government of the Caesars was distinguished to its advantage from that of the republic by the fact that it not merely allowed Greek literati to earn money in Rome, but viewed and treated the great guardianship of Greek science as a part of the sovereignty of Alexander. No doubt, as in this regeneration of the empire as a whole, the building-plan was grander than the building. The royally patented and pensioned Muses, whom the Lagids had called to Alexandria, did not disdain to accept the like payments also from the Romans; and the imperial munificence was not inferior to the earlier regal. The fund for the library of Alexandria and the fund for free places for philosophers, poets, physicians, and scholars of all sorts,[243] as well as the immunities granted to these, were not diminished by Augustus, and were increased by the emperor Claudius--with the injunction, indeed, that the new Claudian academicians should have the Greek historical works of the singular founder publicly read year by year in their sittings. With the first library in the world Alexandria retained at the same time, through the whole imperial period, a certain primacy of scientific work, until Islam burnt the library and killed the ancient civilisation. It was not merely the opportunity thus offered, but at the same time the old tradition and turn of mind of these Hellenes, which preserved for the city that precedence, as indeed among the scholars the native Alexandrians are prominent in number and importance. In this epoch numerous and respectable labours of erudition, particularly philological and physical, proceeded from the circle of the _savants_ “of the Museum,” as they entitled
