Abstract
We consider the effect of converging photospheric motions acting upon a sheared cylindrically-symmetric line-tied arcade. The motions drive a reconnection process whereby a helical structure is formed, in which cool, dense plasma may accumulate at the lowest points of the helical windings thus creating a prominence.
