Scales:  judgment

2 Corinthians 5:10
For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad.

 

The Southern Cross:

Jesus died for our sins, goes along with the scales.
 
The Northern Crown:

The Southern Cross connects with the Northern Crown.  The Greeks say this was a bridal gift.  

The Greeks say that this was the bridal gift of Bacchus to Ariadne, the woman who through her love for Theseus cam to her death by the hand of Artemis, or, according to another story, was so ill treated in her affection that she put an end to her own life, but was saved by the god, who became so pleased with her beauty that he raised her to a place among immortals, and gave her this crown of stars.
