ROSENCRANTZ
Nay, their endeavor keeps in the wonted
pace. But there is, sir, an aerie of children, little
eyases, that cry out on the top of question and are
most tyrannically clapped for 't. These are now the
fashion and so berattle the common stages (so they
call them) that many wearing rapiers are afraid
of goose quills and dare scarce come thither.
(2.2.361-367)
Time for Shakespeare to get in a little contemporary dig at the fashion for children's acting companies, which posed a pretty significant threat to adult theater groups. Rosencrantz calls child actors "eyases" (young hawks), suggesting that these kid actors were threatening the livelihood of the adults. (Just wait ten years, guys: they'll be racking up DUIs and checking into rehab, like all child stars.)
