Here's another riddle

There is box a box in front of you that has five round indentations. You have three coins that will fit these slots. One coin depicts the image of a serpent, another one shows the image of a blindfolded woman, and the last one shows a picture of an old man. You are required to place these coins in the correct slots in order to open the box.

You have only this riddle to help you decide where to place the coins.

"Like coins in the hazy
aether tossed
Our souls must by
their sinful weight
Descend to earth
with lightness lost

To "right" the sins
that they hath laid
When thrice in falling they intone
The Happiness shall be thy own

The first note be not by
the Horned One rung
Though it be there that
all sins be sprung

The Bringer of Life and
the Bringer of Shame
The sins of the latter be
even more tame

Though coming
in the Aged One's wake
The Formless One's soul
in fear doth quake

The Needless One, silent,
with hungers all sated
Is least then in sin
with his lusts all abated

For the gravest of sinners
His place be appointed
And if he be lucky
May his soul be anointed"
