The Calamus Poets Society derives its name from the Calamus Cluster of poems in the legendary volume of poetry Leaves of Grass by Walt Whitman.
It is generally believed that Walt Whitman was a gay man. In his Calamus Cluster of poems, the subject manner is decidedly homoerotic, as in "We two boys together clinging,
One the other never leaving..." One of the links below provides the complete text of the Calamus Cluster. We encourage you to read it for yourself and decide. Most gay men who read it easily identify with it's seeingly timeless themes relevant to our feelings today.
The Calamus herb (also known as the "Sweet Flag" with official name "Acorus Calamus") has been considered a homoerotic symbol since ancient times. Take a look at the picture here and you can see why. It derives it's name from a figure in Greek mythology, Kalamos, who turned into a reed out of grief for his young male lover Karpos who drowned. The Calamus herb also frequents pond and stream areas where closeted gay men of the nineteenth met clandestinely.
