No castle builder of the days when artillery had come into use would have set this fortress on the shore beneath the Pizzofalcone, whence it could be so easily bombarded. It is rather curious to sit under these old walls, and turn one's eyes in succession to the three castles of the city. This is much the oldest, and the least defensible. Then came Castel Nuovo, a little higher in the town; Charles of Anjou founded it; and lastly St. Elmo, high upon the hillside, in a perfect situation, of all others best suited to be the _arx_, or citadel. Why, one wonders, did not the first builders use it, and let the city grow around it? or at least, why did they not place their keep and fortress on the Pizzofalcone? an eminence well suited for defence. Surely those first Greek settlers who came across the hills from Cumæ could not have overlooked the merits of this site! Perhaps, as some scholars hold, Neapolis, "the new city," could not be built upon the Pizzofalcone because Palæopolis, "the old city," was already there. I cannot tell. There are no answers to these questions, which recur again and again as one wanders round these coasts, none the less absorbing because one must speculate on them in vain. But in Naples one must not spend time in chasing shadows. I have still to speak about the French bombardment of the enchanted castle; but first I will take up the tale of the fall of the House of Aragon where I left it in my last chapter, when King Alfonso, terrified and broken by nameless fear, leapt down shuddering from his throne, and fled from royalty and kingdom, to die a penitent monk in a monastery in Sicily. It was a well-nigh hopeless task for his son Ferdinand to maintain the sceptre thus hastily thrust into his hands. The French were already over the borders of his kingdom. They had stormed and sacked the Castle of Monte di San Giovanni, putting the garrison to the sword. "This," says Guicciardini with scornful bitterness, "was the sum of the opposition and trouble which the King of France met with in the conquest of a realm so noble and so splendid; in the defence of which there was shown neither skill, nor courage, nor good counsel, no desire for honour, no strength, no loyalty." The Neapolitans were strongly posted at San Germano, the River Garigliano flowing like a moat in front, and their flanks guarded by lofty mountains; but they fled without a blow, before they even saw the French, leaving their guns behind, and falling back on Capua.
