This paper gives a new characterization of the dimension of a normal Hausdorff space, which joins together the Eilenberg-Otto characterization and the characterization by finite coverings. The link is furnished by the notion of a system of faces of a certain type (N 1,..., N K ), where N 1,..., N K , K are natural numbers. It is shown that a space X contains a system of faces of type (N 1,..., N K ) if and only if dim(X) ≥ N 1 + … + N K . The two limit cases of the theorem, namely N k = 1 for 1 ≤ k ≤ K on the one hand, and K = 1 on the other hand, give the two known results mentioned above.
