Even less is known of the poem called the “Great Works”: the title implies that it was similar in subject to the second section of the “Works and Days”, but longer. Possible references in Roman writers [1106] indicate that among the subjects dealt with were the cultivation of the vine and olive and various herbs. The inclusion of the judgment of Rhadamanthys (frag. 1): ‘If a man sow evil, he shall reap evil,’ indicates a gnomic element, and the note by Proclus [1107] on “Works and Days” 126 makes it likely that metals also were dealt with. It is therefore possible that another lost poem, the “Idaean Dactyls”, which dealt with the discovery of metals and their working, was appended to, or even was a part of the “Great Works”, just as the “Divination by Birds” was appended to the “Works and Days”.
