Abstract

Astrologia by Ottavio Pisani is a scientific treatise printed in 1613. It is a rare example of a big size movable

book, provided with astronomical plates. Most of the plates consists of different overlying rotating paper

discs, useful for making astronomical calculations.

The copy belonging to the Casanatense Library in Rome has recently undergone conservation treatments

at ICPAL, giving us the opportunity to study this kind of artefact for the first time.

The main problem we focused on was reassembling all the volvellae that were detached from the volume.

To do that, it was extremely important to learn how to name and describe all the different parts of the volume

as well as to study how these artefacts were produced. In addition, the book has been compared to a

color copy owned by Galileo Museum in Florence. Furthermore, due to the big size of the book, we tried

to develop guidelines for its safe handling and use.
