Kind of like Cambell and Triamond, Canacee and Cambine, their respective wives and sisters (no, not Sisterwives) cannot be thought of separately. Picking up on the friendship of their husbands, these two ladies quickly become both devoted wives and fast friends themselves.
And while the friendship between their husbands ultimately receives the most attention in the poem, both Canacee and Cambine play crucial roles in establishing and enabling that friendship.
It's Canacee's hand in marriage that initially brings Triamond to Cambell's tournament, and its Cambine's magical intervention that assures harmony between the two men almost on the brink of destroying the other. Their pretty direct agency in bringing Cambell and Triamond together in friendship suggests something emphasized again and again in the text: marriage doesn't take away from friendship but actually facilitates it.
