"17 October 1644. ... 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."
