Foreword by the astronomer Manos Danezis , Professor Emeritus of the University of Athens.

The work of Aratus of Soleus (4th - 3rd century BC) "Phenomena ke Diosimeiia" is a great poetic and astronomical monument of Ancient Greece. It is a purely scientific poem which, with 1155 dactylo hexameter verses, deals with the destruction, the celestial cycles, the rising and setting of the constellations and the weather signs.

The younger critics of the sciences divide the poem into two parts, mainly "Phenomena" and "Diominesia". The first part is a measured presentation of the work of Eudoxus "Phenomena", which has been lost, while the second has been influenced by the work of Theophrastus "On signs of waters and spirits and winters and eudia".
