The explanation of the Urania project (Alena Hadravová, Petr Hadrava):

The interdisciplinary project incorporated with the title Urania into the project Clavis Monumentorum Litterarum dates back to its initiator, Czech historian of astronomy, Dr. Zdenek Horsky (1929-1988). Its aim is to study the original medieval and early modern astronomical texts and to make them accessible in the form of (critical) editions with commented translations. In the case of some rare medieval manuscripts and old prints, the modern edition or some other form of documentation (e.g. digitalization) means their rescue for the history. In all cases, even of quite famous texts, the application of the principle ad fontes enables either to verify but often also to revise the opinions claimed in the secondary literature.

Reliable editions and translations of scientific texts cannot be done without complete understanding of their meaning and a good knowledge of related problems. This is why the cooperation of classical philologist and specialist in the particular science is inevitable.

From the nowadays point of view the astronomy may seem to be a relatively unimportant discipline in the large variety of sciences, many of which are of much higher and immediate practical use. However, in the past the astronomy was crucial for orientation of mankind in time and space. As a one of the septem artes liberales it played very important role in the medieval education. Its importance in that time was also strengthened by the astrological believes applied in many other fields (e.g. in the medicine) and by the importance of the cosmological ideas for the society. But first of all, it must not be forgotten, that the astronomy was one of the cornerstones of the scientific revolution which promoted the rise and development of modern society. It is given by the subject of its study that also the nowadays astronomy or astrophysics is a frontier of the science. This is why the mutual influence of astronomy and culture in general is of particular interest. Another reason, why the history of astronomy attracts traditionally much larger attention than other sciences is that due to the slowness of most astrophysical processes, the historical records can only partly be substituted by the increase of precision of modern instruments (while in most other experimental sciences the old data surpassed by new ones are mostly useless).

In the framework of the present project has been studied e.g. the following texts:
