The name Iphianassa occurs only once in Latin literature—in the proem to De Rerum Natura. Here Lucretius illustrates the evils of religion with a description of Iphianassa's sacrifice at Aulis :illud in his rebus uereor, ne forte rearisimpia te rationis inire elementa uiamqueindugredi sceleris. quod contra saepius illareligio peperit scelerosa atque impia facta.Aulide quo pacto Triuiai uirginis aramIphianassai turparunt sanguine foedeductores Danaum delecti, prima uirorum.cui simul infula uirgineos circumdata comptusex utraque pari malarum parte profusast,et maestum simul ante aras adstare parentemsensit (...) et hunc propter ferrum celare ministrosaspectuque suo lacrimas effundere ciuis,muta metu terram genibus summissa petebat.nec miserae prodesse in tali tempore quibatquod patrio princeps donarat nomine regem.nam sublata uirum manibus tremibundaque ad arasdeductast, non ut sollemni more sacrorumperfecto posset claro comitari Hymenaeo,sed casta inceste nubendi tempore in ipsohostia concideret mactatu maesta parentis,exitus ut classi felix faustusque daretur.tantum religio potuit suadere malorum.It is clear that Lucretius treats the name Iphianassa as a synonym for Iphigenia. Homer and Sophocles mention a daughter of Agamemnon called Iphianassa, but in neither author is she the daughter who was sacrificed at Aulis. The first known mention of this myth was in the Cypria, where, according to the summary of Proclus, the daughter was called Iphigenia. Hesiod refers to it in the Catalogue of Women, where he calls the daughter Iphimede. From the fifth century b.c.e., the extant sources, beginning with Pindar and Aeschylus, call her Iphigenia.
