Aeschylus fr. 124 from Lykourgos (from Athenaeus 10.447c)

“He used to drink beer from these [heads] once he dried them
And then boast proudly about it in his man-cave.”

κἀκ τῶνδ᾿ ἔπινε βρῦτον ἰσχναίνων χρόνῳ
κἀσεμνοκόμπει τοῦτ᾿ ἐν ἀνδρείᾳ στέγῃ

The note from the Loeb attributes an understanding of this fragment to Hermann who compares it to Nonnos, Dionysiaca, 20.149–153, 166–181

Nonnos, Dion. 20.149-153

“The was a certain murderous man living there, of Ares’s line
Who was a mimic of his father’s wretched customs.
The criminal would drag faultless strangers to their doom,
That dread maniac Lykourgos, and then when he cut off
Their mortal heads with steel he hung them in his doorway…”

ἔνθα τις, ῎Αρεος αἷμα, μιαιφόνος ᾤκεεν ἀνήρ,
ἤθεσι ῥιγεδανοῖσιν ἔχων μίμημα τοκῆος,
ὀθνείους ἀθέμιστος ἀμεμφέας εἰς μόρον ἕλκων,
αἰνομανὴς Λυκόοργος· ἀποκταμένων δὲ σιδήρῳ
ἔστεφεν ἀνδρομέοισιν ἑὸν πυλεῶνα καρήνοις
