  We consider the compactification of the 6d N=(2,0) theories, or equivalently
of M-theory 5-branes, on a punctured Riemann surface times a circle. This gives
rise to what we call 3d N=4 Sicilian theories, and we find that their mirror
theories are star-shaped quiver gauge theories. We also discuss an alternative
construction of these 3d theories through 4d N=4 SYM on a graph, which allows
us to obtain the 3d mirror via 4d S-duality.
