The headword -- which literally means oak-holders (because the keels of warships were traditionally made of oak: Theophrastus, Enquiry into Plants 5.7.2) -- is translated 'stocks' by Lionel Casson, Ships and Seamanship in the Ancient World (Baltimore 1995) 223 (cf. 392). He writes there: 'Homer describes the row of axes through which Odysseus made his celebrated shot as being set up "like stocks" (Od. 19.574; for a convincing reconstruction see A. Wace and F. Stubbings, A Companion to Homer (London 1962) 534-35. The expression e)c druo/xwn aut sim. "from the stocks", used literally in e.g. Polybius 1.38.5 [...], could also mean figuratively "from scratch" (e.g. Plato, Timaeus 81B)'.
[1] From the scholia to Aristophanes, Thesmophoriazusae 52, quoted below.
[2] Aristophanes, Thesmophoriazusae 52-57 (web address 1 below), where the mss have xoaneu/ei ("he is smelting") for the Suda's xianeu/ei. See also chi 297 which quotes this line. Aristophanes is ridiculing the style of Agathon, an Athenian poet of the late fifth century BC made famous by Plato’s Symposium. In this play Aristophanes represents him as affected and effeminate, as poet and as person, and brings him onto the stage in female dress. But note that four years later, in Frogs 85, Aristophanes defines Agathon as a)gaqo\s poihth\s kai= poqeino\s toi=s fi/lois, "a good poet and missed by friends" (see under alpha 124). On Agathon see also mu 1445, pi 1165, chi 403.
[3] Greek Anthology 6.16.5-6 (tr. H. Beckby). On this epigram, in which three brothers dedicate their different types of hunting nets to Pan, see Gow and Page (vol. I, 400-401), (vol. II, 436), and another excerpt from this epigram at sigma 659.
[4] From the scholia to Plato, Timaeus 81B (probably via Timaeus Sophista, Platonic Lexicon delta983b); see already above. Likewise in Photius, Lexicon delta767 (both the Suda and Photius use Timaeus Sophista as an additional source).
[5] Quotation (via the Excerpta Constantini Porphyrogeniti, in Adler's view) unidentifiable.
