In Smith's "Dictionary of Greek and Roman Biography and Mythology.", the entry for the Pleiades states:
According to another story, the Pleiades were virgin companions of Artemis, and, together with their mother Pleione, were pursued by the hunter Orion in Boeotia; their prayer to be rescued from him was heard by the gods, and they were metamorphosed into doves (peleiades), and placed among the stars (Hygin. Poet. Astr. ii. 21; Schol. ad Apollon. Rhod. iii. 226; Pind. Nem. ii. 17).
Following up the citations:
Hyginus, Astronomica 2.21 doesn't mention Artemis, although it does mention all the other elements of the story - Orion, Boeotia, etc.
Pindar's Nemean Odea only makes a brief remark anout Orion needing (wanting?) to stay close to the Pleiades.
The Scholiast on Apollonius (many thanks to @b-a for directing me to https://archive.org/details/bub_gb_oBI-AAAAcAAJ/page/n573 and https://archive.org/details/bub_gb_oBI-AAAAcAAJ/page/n575) I'm less sure about, since I don't know the Greek language well. But I cannot see the name "Artemis" (Αρτεμις) there at all.
Am I correct that none of these three sources refer to any possible link between Artemis and the Pleiades? Or can someone fluent in Greek see something in the Scholiast I couldn't?
(As a possible follow-up question... is there anything in the texts and scholiasts that does state "Yes, the Pleiads were among Artemis's companions", or indeed testify to any link other than Taygete giving her the Hind?)
