It looks as though Homer, in this dubious prolepsis, were himself referring to an ambiguous tradition, or rather — since nothing in the present case prevented him from choosing, as did his continuators after him — as though he wished to leave them an open field by merely indicating the two possible roads to follow.

As this is accomplished, the women are suddenly awakened to the various ways in which they have not yet shed the chains of the past, and as in a perfectly wrought prolepsis, intuit one another as the necessary tools with which to do so.
-- Terri Ginsberg, "Entre Nous, Female Eroticism, and the Narrative of Jewish Erasure", Romancing the Margins?, 2000

Prolepsis came to English in the mid-1400s from the Ancient Greek prolambanein literally meaning "to take before."
