We went hence to the Palace of the Dukes, where is also the Court of Justice; thence to the Merchant's Walk, rarely covered. Near the Ducal Palace we saw the public armory, which was almost all new, most neatly kept and ordered, sufficient for 30,000 men. We were showed many rare inventions and engines of war peculiar to that armory, as in the state when guns were first put in use. The garrison of the town chiefly consists of Germans and Corsicans. The famous Strada Nova, built wholly of polished marble, was designed by Rubens, and for stateliness of the buildings, paving, and evenness of the street, is far superior to any in Europe, for the number of houses; that of Don Carlo Doria is a most magnificent structure. In the gardens of the old Marquis Spinola, I saw huge citrons hanging on the trees, applied like our apricots to the walls. The churches are no less splendid than the palaces; that of St. Francis is wholly built of Parian marble; St. Laurence, in the middle of the city, of white and black polished stone, the inside wholly incrusted with marble and other precious materials; on the altar of St. John stand four sumptuous columns of porphyry; and here we were showed an emerald, supposed to be one of the largest in the world. The church of St. Ambrosio, belonging to the Jesuits, will, when finished, exceed all the rest; and that of the Annunciada, founded at the charges of one family, in the present and future design can never be outdone for cost and art. From the churches we walked to the Mole, a work of solid huge stone, stretching itself near 600 paces into the main sea, and secures the harbor, heretofore of no safety. Of all the wonders of Italy, for the art and nature of the design, nothing parallels this. We passed over to the Pharos, or Lantern, a tower of very great height. Here we took horses, and made the circuit of the city as far as the new walls, built of a prodigious height, and with Herculean industry; witness those vast pieces of whole mountains which they have hewn away, and blown up with gunpowder, to render them steep and inaccessible. They are not much less than twenty English miles in extent, reaching beyond the utmost buildings of the city. From one of these promontories we could easily discern the island of Corsica; and from the same, eastward, we saw a vale having a great torrent running through a most desolate barren country; and then turning our eyes more northward, saw those delicious villas of St. Pietro d'Arena, which present another Genoa to you, the ravishing retirements of the Genoese nobility. Hence, with much pain, we descended toward the Arsenal, where the galleys lie in excellent order.
