Ovid’s Hercules cycle names the Nemean lion’s skin among the labors. A worn hide in that Latin verse, not generic leather and not a minted Heracles as the meeting’s other end.
Virgil’s Aeneid Book 7 seats the lion-skin Aventinus wears in the Italian catalog, Herculean hide-mark of that hero’s line. A named Nemean-hide signal in that epic, not club-of-heracles as the weapon beside it and not a generic fur dump.
from Virgil · Aeneid, 19 BCE (unfinished at the poet’s death)
