The Song of Solomon mentions the name "Solomon" several times. Is it plausible to understand Solomon to have become a symbol of masculinity (a wise, mighty, powerful womanizer), and read references to Solomon as comparisons of the bridegroom to the symbol of masculinity (much like one would understand a man being called "Casanova")?
I am sure there are many ways to read these references, if this is what you wish to do. Apparently this was originally an operetta. Although this poem is attributed to Solomon, the language and style indicate that it was actually written after the end of the Babylonian Exile.
The Song of Solomon tells the sexual experiences and thoughts of a black or dark-skinned woman, but seems to have no real historical or religious significance. However, some find in it a portrayal and praise of the mutual love of God and his people, or an inspired portrayal of ideal human love. Perhaps it can also be seen as comparing the bridegroom to the “masculine ideal.”
