Lima, though obscure, may relate to limen (threshold), guarding transitional zones. In poetic contexts, she symbolizes the delicate boundary between states—sacred/profane, life/death—and the need for ritual caution when crossing into unknown or charged domains.

Lima, though obscure, appears in antiquarian sources as a threshold goddess, possibly a variant of Cardea; her name may relate to “limen” (threshold); she would have protected doorways from evil, like other liminal deities; poets might invoke her in domestic charms or metaphors for transitions; her obscurity highlights how many Roman household deities were local, oral, and lost to time—yet essential to daily religious practice; she exemplifies the Roman sacralization of architectural boundaries.
