 Iamblichus already uses the terminology “hypercosmic” vs. “encosmic” or “pericosmic” (e.g., Reply to Porphyry VIII, 8 [SS-2013: 200.25–27]), inherited from Middle Platonism but destined to become technical in later Neoplatonism. In anticipation of this later use, they are meant to bridge the gap between the Demiurge and the sublunar realm, although their exact role remains unclear (the aforementioned passage speaks of the help they give to souls in their ascent). Such lower entities seem to be produced according to a geometric progression (cf. In Timaeum [D-1973: Fr. 79]). The terminological continuity allows one to conceive of Iamblichus’ system as the matrix for later variations, particularly Proclus’ one, although it is to be noted that no text bears witness to the presence of Proclus’ intermediate “intelligible-intellective” and “hypercosmic-encosmic” levels in Iamblichus.
