'Phaedra vestigatrix': allusione senecana ad un motivo elegiaco in Phd. 613-614

In Phaedra 613-4 Seneca describes Phaedra’s mad fantasies: she dreams of following Hippolytus in a winter-landscape as a vestigatrix, a servant carrying nets to capture game. This sounds as a veiled allusion at the protagonist’s order to his servants in the prologue ‘Scandite colles semper canos/ nive Riphaea’ (vv. 7-8). If so, Phaedra’s words would relate to the elegiac commonplace of the vestigatio, part of the servitium amoris motive.
