"The Phaenomena is a didactic epic poem modelled on Hesiod's Works and Days and cleverly updated to appeal to contemporary readers interested in new trends in Greek poetry, philosophy and science. Aratus invokes a beneficent Stoic Zeus who has created the constellations and their movements to help men follow the progress of the solar year, and also provides a great variety of signs in sky, air, earth and sea as warnings of weather changes." "This volume presents for the first time in English an edition of the poem with a full introduction, a facing translation and a line by line commentary. The introduction explains the literary and scientific background, the characteristic features of Aratus' language, style and metre, and the transmission of the text to the end of the Middle Ages. The commentary gives help with the content of the poem and aims to discuss and resolve the many problems of text and interpretation caused by Aratus' innovative use of language. The text is based on a new reading of the MSS, including one not used before."--BOOK JACKET.
