Given
The most important function EP → TV of epic poetry is to transmit the values by which a group of people is to live.
This transmission [of values] TV → HF is accomplished not by an explicit discussion of those values, but rather by their embodiment in heroic figures, who are presented as role models.
Imitating those role models HF → MD [heroic figures] gives meaning and direction to the lives of those who hear the poems.
