On the Morning of Christ's Nativity

In On the Morning of Christ's Nativity, written in 1629, John Milton envisions the arrival of Christ as toppling the world of pagan spirits and deities. Each stanza describes the fall of a different regional or national paganism. Two stanzas are devoted to Roman religion: 

The lonely mountains o'er,

And the resounding shore,

A voice of weeping heard and loud lament;

Edged with poplar pale

From haunted spring, and dale

The parting genius is with sighing sent;

With flower-inwoven tresses torn

The Nymphs in twilight shade of tangled thickets mourn.

 In consecrated earth,

And on the holy hearth,

The Lars and Lemures moan with midnight plaint;

In urns and altars round,

A drear and dying sound

Affrights the Flamens at their service quaint;

And the chill marble seems to sweat,

While each peculiar power forgoes his wonted seat.

*     *     *     *     *     *     *     *     *

With flower-inwoven tresses torn / The Nymphs in twilight shade of tangled thickets mourn.

I think it wouldn't be like this. The nymphs of the twilight forest edges would be too pure-hearted to do anything but celebrate too, on the morning of Christ's nativity.
