In the first half of the Twelfth Dynasty, proportions of the human figure returned to the traditional Memphite style of the Fifth and early Sixth Dynasties.[87] Male figures had broad shoulders, a low small of the back, and thick muscular limbs. Females had slender figures, a higher small of the back and no musculature.[87] In this period, sketches for the production of statues and reliefs were laid out on a squared grid, a new guide system. Since this system contained a greater number of lines, it allowed more body parts to be marked.
