Helmets using ivory from boars' tusks were known in the Mycenaean world from the 17th century BC to the 10th century BC. The helmet was made through the use of slivers of boar tusks which were attached to a leather base, padded with felt, in rows. A description of a boar's tusk helmet appears in book ten of Homer's Iliad, as Odysseus is armed for a night raid to be conducted against the Trojans.Meriones gave Odysseus a bow, a quiver and a sword, and put a cleverly made leather helmet on his head. On the inside there was a strong lining on interwoven straps, onto which a felt cap had been sewn in. The outside was cleverly adorned all around with rows of white tusks from a shiny-toothed boar, the tusks running in alternate directions in each row. Μηριόνης δ' Ὀδυσῆϊ δίδου βιὸν ἠδὲ φαρέτρην καὶ ξίφος, ἀμφὶ δέ οἱ κυνέην κεφαλῆφιν ἔθηκε ῥινοῦ ποιητήν: πολέσιν δ' ἔντοσθεν ἱμᾶσιν ἐντέτατο στερεῶς: ἔκτοσθε δὲ λευκοὶ ὀδόντες ἀργιόδοντος ὑὸς θαμέες ἔχον ἔνθα καὶ ἔνθα εὖ καὶ ἐπισταμένως: μέσσῃ δ' ἐνὶ πῖλος ἀρήρει.
