It all served to fog my mind with pleasure so that I forgot my Grandpa's repeated warnings, and one night left Maheegun unchained.

这一切使我高兴过了头，结果有一天晚上我忘记了爷爷的再三叮嘱，没有把美尔根拴起来。

They must be unchained or they'll waste away.

必须解开枷锁 否则它们会日渐衰弱。

As a reward, Zeus unchained Prometheus from the bolder in  the Caucasus mountains and instead wrapped two bindings of stone and iron around the Titan's  finger to commemorate his original punishment.

作为奖赏，宙斯从高加索山区的勇者手中解开了普罗米修斯的锁链，并在泰坦的手指上缠上了两根石头和铁的绑带，以纪念他最初的惩罚。

The front door stood open, but the jealous gate was fastened, as at my last visit; I knocked, and invoked Earnshaw from among the garden beds; he unchained it, and I entered.

前门开着，可是像我上次拜访一样，那专为提防外人的栅门是拴住的：我敲了门，把恩萧从花圃中引出来了；他解开了门链，我走进去。
