How change font size of Graph vertex labels?

I want to make the "Names" labels of vertices in a Graph larger. The
"obvious" way...

Graph[{1, 2, 3},
{DirectedEdge[1, 2], DirectedEdge[2, 3], DirectedEdge[3, 1]},
{VertexLabels -> {Placed["Name", Center]}, VertexSize -> {Medium},
VertexStyle -> {24}}]

...seems to do nothing. And replacing the option VertexStyle -> {24}
with the wordier VertexStyle -> {FontSize->24} prevents Mathematica from
evaluating the Graph expression at all.
