west's arguments have been highly influential, but other scholars have arrived at different conclusions using the same evidence. fowler thinks that the sicyon genealogy would more likely reflect a composition before cleisthenes' death (c. 575 bce) and dates the poem to the period closely following the first sacred war (595–585 bce), connecting its content to the growing influence of the amphictyonic league and placing its author in aeolian thessaly because of the aeolid family-trees centered around that region which dominate the earlier portions of the poem. hirschberger, on the other hand, takes this focus upon the aeolids and the "catalogue" poet's perceived interest in eastern peoples to be indicative of a poet from aeolis in asia minor; she proposes that the "catalogue" was composed there between 630 and 590 bce, viewing the composition of the "shield of heracles" and an apparent allusion to the poem by stesichorus (died c. 555 bce) as providing the ultimate "terminus ante quem".
