Of the second Piece.
THE second Piece of the Pyramis is also a round Table, almost like the former, but somewhat less; having only thirty inches in diameter, about the thickness of the first, held up by four iron Sup∣porters. The Edge or Circumference of this Table is cut into six∣teen equal Planes, all made hollow, and covered with Glass, like those of the first Table; but they differ from them in this, that here the Dyals are not described on the Glass Covers, but on the bottom of the Boxes: neither do they shew the Hour, but the different Ri∣sing of the more remarkable Stars, according to the three manners of Risings observed by Astronomers, to wit, the Cosmical Rising, the Acronical, and the Aeliacal, as shall be declared hereafter, when we speak of the Dyals of this second Piece. The Style to each of these Dyals is a little Star painted upon the inside of the Glass-Cover, the better to keep it from the weather.
Out of the sides of this Piece issue also four Branches, towards the East, West, North and South, and carry on each of them a Glass-Bowl to shew the Hour, like those of the first Piece, but in a diffe∣way: for one of them shews the Hour by a Style without a Shadow: another shews it by a Shadow without a Style, &c. whereas those of the first Table shew it by the four Elements, Fire, Water, Air and Earth, as shall be shewed in their due place.
On the upper part of this Table are placed eight reclining Planes; four whereof are covered each of them with a Plate of Looking-glass, on which the Hour-lines, or Style of a Dyal being painted, are re∣flected upon the bottom inclining Planes of the third Piece, and there shew the Hour, as shall be presently demonstrated. The other four have also Dyals upon them, which are to be seen each of them in a
