He completed some important public works, which, though, not numerous, were very useful. The principal were an aqueduct, which had been begun by Caius; an emissary for the discharge of the waters of the Fucine lake, The Fucine Lake is now called Lago di Celano, in the Farther Abruzzi. It is very extensive, but shallow, so that the difficulty of constructing the Claudian emissary, can scarcely be compared to that encountered in a similar work for lowering the level of the waters in the Alban lake, completed A. U. C. 359. and the harbour of Ostia; although he knew that Augustus had refused to comply with the repeated application of the Marsians for one of these; and that the other had been several times intended by Julius Caesar, but as often abandoned on account of the difficulty of its execution. He brought to the city the cool and plentiful springs of the Claudian water, one of which is called Caeruleus. and the other Curtius and Albudinus, as likewise the river of the New Anio, in a stone canal: and distributed them into many magnificent reservoirs. The canal from the Fucine lake was undertaken as much for the sake of profit, as for the honour of the enterprise; for there were parties who offered to drain it at their own expense, on condition of their having a grant of the land laid dry. With great difficulty he completed a canal three miles in length, partly by cutting through, and partly by tunnelling, a mountain; thirty thousand men being constantly employed in the work for eleven years.Respecting the Claudian aqueduct, see CALIGULA, c. xxi. He formed the harbour at Ostia, by carrying out circular piers on the right and on the left, with a mole protecting, in deep water, the entrance of the port.Ostia is referred to in a note, TIBERIUS, c. xi. To secure the foundation of this mole, he sunk the vessel in which the great obeliskSuetonius calls this " the great obelisk " in comparison with those which Augustus had placed in the Circus Maximus and Campus Martius. The one here mentioned was erected by Caligula in his Circus, afterwards called the Circus of Nero. It stood at Heliopolis, having been dedicated to the sun, as Herodotus informs us, by Phero, son of Sesostris, in acknowledgment of his recovery from blindness. It was removed by Pope Sixtus V. in 1586, under the celebrated architect, Fontana, to the centre of the area before St. Peter's, in the Vatican, not far from its former position. This obelisk is a solid piece of red granite, without hieroglyphics, and, with the pedestal and ornaments at the top, is 182 feet high. The height of the obelisk itself is 113 palms, or 84 feet. had been brought from Egypt;Pliny relates some curious particulars of this ship:-"A fir tree of prodigious size was used in the vessel which, by the command of Caligula, brought the obelisk from Egypt, which stands in the Vatican Circus, and four blocks of the same sort of stone to support it. Nothing certainly ever appeared on the sea more astonishing than this vessel; 120,000 bushels of lentiles served for its ballast; the length of it nearly equalled all the left side of the port of Ostia; for it was sent there by the emperor Claudius. The thickness of the tree was as much as four men could embrace with their arms."-B. xvi. c. 76. and built upon piles a very lofty tower, in imitation of the Pharos at Alexandria, on which lights were burnt to direct mariners in the night.

He often distributed largesses of corn and money among the people, and entertained them with a great variety of public magnificent spectacles, not only such as were usual, and in the accustomed places, but some of new invention, and others revived from ancient models, and exhibited in places where nothing of the kind had been ever before attempted. In the games which he presented at the dedication of Pompey's theatre, See AUGUSTUS, c. xxxi. It appears to have been often a prey to the flames, TIBERIUS, c. xli; CALIGULA, c. XX. which had been burnt down, and was rebuilt by him, he presided upon a tribunal erected for him in the orchestra; having first paid his devotions, in the temple above, and then coming down through the centre of the circle, while all the people kept their seats in profound silence. Contrary to the usual custom of rising and saluting the emperor with loud acclamations. He likewise exhibited the secular games, A. U. C. 800. giving out that Augustus had anticipated the regular period; though he himself says in his history, "That they had been omitted before the age of Augustus, who had calculated the years with great exactness, and again brought them to their regular period."The Secular Games had been celebrated by Augustus, A. U. C. 736. See c. xxxi. of his life, and the Epode of Horace written on the occasion. The crier was therefore ridiculed, when he invited people in the usual form, "to games which no person had ever before seen, nor ever would again;" when many were still living who had already seen them; and some of the performers who had formerly acted in them, were now again brought upon the stage. He likewise frequently celebrated the Circensian games in the Vatican, In the circus which he had himself built. sometimes exhibiting a hunt of wild beasts, after every five courses. He embellished the Circus Maximus with marble barriers, and gilded goals, which before were of common stone Tophina; Tuffo, a porous stone of volcanic origin, which abounds in the neighbourhood of Rome, and, with the Travartino, is employed in all common buildings. and wood, and assigned proper places for the senators, who were used to sit promiscuously with the other spectators. Besides the chariot-races, he exhibited there the Trojan game, and wild beasts from Africa, which were encountered by a troop of pretorian knights, with their tribunes, and even the prefect at the head of them; besides Thessalian horse, who drive fierce bulls round the circus, leap upon their backs when they have exhausted their fury, and drag them by the horns to the ground. He gave exhibitions of gladiators in several places, and of various kinds; one yearly on the anniversary of his accession in the pretorian camp, In compliment to the troops to whom he owed his elevation: see before, c. xi. but without any hunting, or the usual apparatus; another in the Septa as usual; and in the same place, another out of the common way,. and of a few days' continuance only, which he called Sportula; because when he was going to present it, he informed the people by proclamation, " that he invited them to a late supper, got up in haste, and without ceremony." Nor did he lend himself to any kind of public diversion with more freedom and hilarity; insomuch that he would hold out his left hand, and joined by the common people, count upon his fingers aloud the gold pieces presented to those who came off conquerors. He would earnestly invite the company to be merry; sometimes calling them his "masters," with a mixture of insipid, far-fetched jests. Thus when the people called for Palumbus,Palumbus was a gladiator: and Claudius condescended to pun upon his name, which signifies a wood-pigeon. he said, " He would give them one when he could catch it." The following was well-intended and well-timed; having, amidst great applause, spared a gladiator, on the intercession of his four sons, he sent a billet immediately round the theatre, to remind the people, " how much it behooved them to get children, since they had before them an example how useful they had been in procuring favour and security for a gladiator." He likewise represented in the Campus Martius, the assault and sacking of a town, and the surrender of the British kings,See before, c. xvii. Described in c. xx. and note. presiding in his general's cloak. Immediately before he drew off the waters from the Fucine lake, he exhibited upon it a naval fight. But the combatants on board the fleets crying out, "Health attend you, noble emperor! We, who are about to peril our lives, salute you;" and he replying, "Health attend you too," they all refused to fight, as if by that response he had meant to excuse them. Upon this, he hesitated for a time, whether he should not destroy them all with fire and sword. At last, leaping from his seat, and running along the shore of the lake with tottering steps, the result of his foul excesses, he, partly by fair words, and partly by threats, persuaded them to engage. This spectacle represented an engagement between the fleets of Sicily and Rhodes; consisting each of twelve ships of war, of three banks of oars. The signal for the encounter was given by a silver Triton, raised by machinery from the middle of the lake.
