Representations of how the ancient Egyptians saw the sky have come down to us in the form of astronomical diagrams that are known from tombs, memorial temples, water clocks, and coffins. An emphatic element of these catalogues of celestial phenomena, comprising both textual and visual information, was the drawings of constellations. They appeared in two groups in the southern and northern panels of the astronomical diagrams. Two different strands of tradition existed about the northern constellations, exemplified by the astronomical diagrams in the tombs of Senenmut and Seti I. Based on the analysis of the arrangement of the constellation figures within these documents, and through the examination of a wide range of relevant sources, the paper using the principle of visual resemblance and the help of planetarium software identifies the star patterns in the sky from which the ancient Egyptian constellations were derived.
