Technical Notes and further information

The printed book used an unusual page-numbering system. Only the recto (front) side of each folio (leaf) had a printed number. In this e-text, the unnumbered verso (back, overleaf) pages are shown in the margin as [v]. In addition, the first two or three leaves in each eight-page signature are numbered: A, A2, A3... B, B2....
Oddities of punctuation are as in the original, but missing full stops at paragraph-end have been supplied.

The Text
This e-text is based on a facsimile edition made from a single copy of the 1592 original. In some places, text is illegible or missing.
“The Italian version” refers to the 1499 text. At time of preparation, page images of this book were available at http://mitpress.mit.edu/e-books/HP/hyp000.htm and linked pages. Note that the 1592 English translation covers just under half the Italian text. Within these pages, the translation reproduces one-third (22 of 70) of the illustrations of the Italian edition, concentrated in the early part of the book. The Italian text was consulted in some cases of uncertain readings in the English. The sidenotes have no Italian equivalent.

Illustrations:
Some pairs of illustrations were printed on facing pages and would have been seen together. They are shown here as thumbnails, along with some facing pages from the Italian version.

Greek and Inscriptions:
The Greek text often introduces additional errors that were not present in the Italian version. Among other problems, the text uses a form of Π (Pi) that is easily confused with Γ (Gamma), and an Υ (Upsilon) that resembles Τ (Tau). The Arabic text could not be transcribed.
