Comment: there is the first formulation of the famous Poincaré-Miranda theorem. Poincaré's work remained unknown during approximately ninety years. Unaware of this work, Brouwer proposed his fixed point theorem in 1909 and Miranda proved the equivalence between the Poincaré-Miranda theorem and the Brouwer fixed point theorem in 1941. Poincaré's work has been re-discovered in the 70's. Poincaré's sketch of the proof seems to show that he had in mind arguments close to the ones proposed in M.N. Vrahatis, A short proof and a generalization of Miranda's existence theorem Proceedings of the American Mathematical Society, 107, No. 3, 701-703, (1989).

Comment: there is an actual parallelepiped method for the approximation of the solution to IVP for ODE. Kruckeberg also mentions inner approximation, though no hint is given on the inner approximation process.
