Common and queer: syntax and sexuality in the Rubáiyát. Erik Gray.
In: FitzGerald’s Rubáiyát of Omar Khayyám. Popularity and Neglect. Cambridge, Anthem Press, 2011. pp. 27–44.

Gray contends that FitzGerald’s Rubáiyát originally achieved its giddy popularity because it seemed so strange and daring, yet the poem’s very familiarity has tended to obscure what is most exceptional about it, its often puzzling language and its depiction of relations between men.
