Mallia Quartier 18 and the Palaikastro Kouros Rooms: Two Homologies

On the S side of the Palace at Mallia there is a group of rooms that has been strongly associated to ritual, which seems to be remarkably similar in the conception of the architecture to a group of rooms in Palaikastro where the remnants of the celebrated Kouros of Palaikastro were found. The conceptual similarities are so stark that would argue in favour of a similar use (ritual?) of the two complexes. This is interesting however, since at Mallia two large clay feet of a larger statue were found and at Palaikastro the remnants of the Kouros. Are these the first examples of cult statues that we have attested?
