[Footnote 599: With no boundaries.--Ver. 42. The 'limes' was a line or boundary, between pieces of land belonging to different persons, and consisted of a path, or ditch, or a row of stones. The 'ager limitatus' was the public land marked out by 'limites,' for the purposes of allotment to the citizens. On apportioning the land, a line, which was called 'limes,' was drawn through a given point from East to West, which was called 'decumanus,' and another line was drawn from North to South. The distance at which the 'limites' were to be drawn depended on the magnitude of the squares or 'centuriæ,' as they were called, into which it was purposed to divide the tract.] [Footnote 601: Then was the shore.--Ver. 44. Because they had not as yet learnt the art of navigation.] [Footnote 602: Turreted fortifications.--Ver. 47. Among the ancients the fortifications of cities were strengthened by towers, which were placed at intervals on the walls; they were also generally used at the gates of towns.] [Footnote 603: Why not seek the heavens.--Ver. 50. With what indignation would he not have spoken of a balloon, as being nothing less than a downright attempt to scale the 'tertia régna!'] [Footnote 604: Ciesar but recently.--Ver. 52. See the end of the Fifteenth Book of the Metamorphoses, and the Fasti, Book iii. 1. 704.] [Footnote 605: The Senate-house.--Ver. 55. 'Curia'was the name of the place where the Senate held its meetings, such as the 'curia Hostilia,' * Julia,' Marcelli,' and others. Hence arose the custom of calling the Senate itself, in the various Roman towns, by the name of 'curia,' but not the Senate of Rome. He here means to say, that poverty excluded a man from the Senate-house, and that wealth alone was the qualification for the honours of the state.] [Footnote 606: Wealth alone confers honours --Ver. 55. The same expression occurs in the Fasti, Book i. 1. '217, where a similar complaint is made on the worldly-mindedness of the age.] [Footnote 607: The Field of Mars.--Ver. 57. The 'comitia,' or meetings for the elections of the magistrates, were held on the 'Campus Martius' or field of Mars. See the Notes to the Fasti, Book i. 1. 53.]
