A Trumpeting Angel.
The angel blowing a horn memorial refers to the following passage of the Bible which states the end of days, stated by 7 angels blowing 7 horns:
'And the third angel sounded, & there fell a great star from heaven, burning as it were a lamp, & it fell upon the third part of the rivers, & upon the fountains of waters; And the name of the star is called Wormwood: & the third part of the waters became wormwood; & many men died of the waters, because they were made bitter. (Revelation 8:10-11)'
'Wormwood' is the Ukrainian word for Chernobyl & thus some believe that the Bible actually predicted the disaster at the power plant & subsequent contamination 'including the nearby rivers'.
