A parallelipipedon is a solide figure comprehended vnder foure playne qua∣drangle figures, of which those which are opposite are parallels.
As in playne superficieces a parallelogramme is that which is contained
There is also in these bookes following, mencion made of solides, whose two bases are Poligonon figures, lyke, equall, equilater, and parallels, and the sides set vpon the bases are parallelogrammes: which kynde of solides Cam∣pane calleth sided Columnes (and which as was before noted, may be cōpre∣ded vnder the definition of a Prisme) a forme wherof although grosely•• be∣hold in this example, whose bases are two like equall, equilater, equiangle, and parallel hexagons, and the sides set vppon those bases are sixe parallelo∣grāmes: ye may better cōceiue the forme therof by
Because these fiue regular bodies here defined are not by these figures here set, so fully and liuely expressed, that the studious beholder can through∣ly according to their definitions conceyue them. I haue here geuen of them other descriptions drawn in a playne, by which ye may easily attayne to the knowledge of them. For if ye draw the like formes in matter that wil bow and geue place, as most apt∣ly ye may do in fine pasted paper, such as pastwiues make womēs pastes of, & thē with a knife cut eue∣ry line finely, not through, but halfe way only, if thē ye bow and bende them accordingly, ye shall most plainly and manifestly see the formes and shapes of these bodies, euen as their definitions shew. And it shall be very necessary for you to had•• ••tore of that pasted paper by you, for so shal yo•• vpon it 〈…〉〈…〉 the formes of other bodies, as Prismes and Parallelipopedons, 〈…〉〈…〉 set forth in these fiue bookes following, and see the very 〈◊〉〈◊〉 of th••se bodies there mēcioned: which will make these bokes concerning bodies, as easy vnto you as were the other bookes, whose figures you might plainly see vpon a playne superficies.
