Adler cites as a comparandum Lexicon Ambrosianum 22, 23, 28.
[1] This suppletion is suggested by the corresponding entry in the Lexicon of pseudo-Zonaras 5.1, which is identical to this entry apart from the headword phrase: vs. *)aba/nteios here, ps.-Zonaras has *)aba/nteios do/mos ('Abantian house'). The headword here could serve as a modifier for any substantive of the masculine gender, including a son or descendant, as is suggested by the subsequent reference to a patronymic form. The adjective is unattested outside of grammars and lexica, and ps.-Zonaras provides the only example of it modifying a specific substantive. Stephanus of Byzantium in his entry on 'Abantis', an early name for Euboea (cf. Hesiod fr. 296 Merkelbach-West), notes it as the possessive adjective relating to the Abantes or to their legendary founder Abas, whom Stephanos identifies either as the son of Lynkeus (see note 2 below) or a homonymous son of Poseidon. Cf. also Herodianus Peri orthographias 3.2.429.34 and 465.14.
[2] Not the Abas of alpha 20, but one of the mythological figures of that name; in fact almost certainly A. the son of Lynkeus, king of Argos [Myth, Place] after Danaos and father of the twins Akrisios and Proitos (Pausanias 2.16.2 (web address 1); Apollodorus, Library 2.2.1 (web address 2)).
[3] This term is used by (e.g.) Ovid both for an actual son of Abas (Metamorphoses 4.607 (Acrisius): web address 3) and in the sense of a more distant descendant (4.673 (Perseus, great-grandson of Abas; cf. pi 1372): web address 4).
