The _Rhombus_ or Lozenge figure so visible in this order, was also a remarkable form of battle in the _Grecian_ Cavalry,[141] observed by the _Thessalians_, and _Philip_ King of _Macedon_, and frequently by the _Parthians_, As being most ready to turn every way, and best to be commanded, as having its ductors, or Commanders at each Angle. [141] Ælian. Tact. The _Macedonian Phalanx_ (a long time thought invincible) consisted of a long square. For though they might be sixteen in Rank and file, yet when they shut close, so that the sixt pike advanced before the first, though the number might be square, the figure was oblong, answerable unto the Quincuncial quadrate of _Curtius_. According to this square _Thucydides_ delivers, the _Athenians_ disposed their battle against the _Lacedemonians_ brickwise,[142] and by the same word the Learned _Guellius_ expoundeth the quadrat of _Virgil_[143] after the form of a brick or tile. [142] ἐν πλασίω. [143] Secto via limite quadret. _Comment._ in Virgil. And as the first station and position of trees, so was the first habitation of men, not in round Cities, as of later foundation; For the form of _Babylon_ the first City was square, and so shall also be the last, according to the description of the holy City in the Apocalyps. The famous pillars of _Seth_ before the floud had also the like foundation, if they were but _antidiluvian_ Obelisks, and such as _Cham_ and his _Ægyptian_ race, imitated after the Floud. But _Nineveh_ which Authours acknowledge to have exceeded _Babylon_, was of a longilaterall[144] figure, ninety five Furlongs broad, and an hundred and fifty long, and so making about sixty miles in circuit, which is the measure of three dayes journey, according unto military marches, or castrensiall mansions. So that if _Jonas_ entred at the narrower side, he found enough for one dayes walk to attain the heart of the City, to make his Proclamation, And if we imagine a City extending from _Ware_ to _London_, the expression will be moderate of six score thousand Infants, although we allow vacuities, fields, and intervals of habitation, as there needs must be when the monument of _Ninus_ took up no lesse then ten furlongs.
