I create a matrix.

basis = {{1, 0}, {0, 1}}

Which I want to become a graphic. This code works fine

Graphics[{Blue, Rectangle[basis[[1]], basis[[2]]]}, Axes -> True, 
 PlotRange -> {{0, 10}, {0, 10}}]

But this does not, although it seems to me to be the same

Graphics[{Blue, Rectangle[#1, #2] & /@ basis}, Axes -> True, 
 PlotRange -> {{0, 10}, {0, 10}}]
