If wool delight thee, first, be far removedAll prickly boskage, burrs and caltrops; shunLuxuriant pastures; at the outset chooseWhite flocks with downy fleeces. For the ram,How white soe'er himself, be but the tongue'Neath his moist palate black, reject him, lestHe sully with dark spots his offspring's fleece,And seek some other o'er the teeming plain.Even with such snowy bribe of wool, if earMay trust the tale, Pan, God of Arcady,Snared and beguiled thee, Luna, calling theeTo the deep woods; nor thou didst spurn his call.
