This study investigates the potential shadow-tracking functionality of Pillars 18 and 31 in Enclosure D at the Pre-Pottery Neolithic site of Portasar (G¨obekli Tepe). Based on simplified threedimensional modeling, photometric analysis, and simulations using Stellarium 24, the research focuses on the midday shadow dynamics during the year’s key solar events: the solstices and equinoxes. The findings indicate that the grooves on the upper sections of the Pillars, as well as symbolic carvings—such as the bucranium, the “H” symbol, and the “lunisolar” motif—may have served as solar or lunar shadow markers aligned with the culmination points of the Sun and the Moon. Specifically, the bucranium appears to correspond to the culmination of the Taurus constellation (particularly the Pleiades), while the position of the “lunisolar” symbol coincides with the equinoctial noon and possibly with lunar or solar eclipses. These results support the hypothesis that the central Pillars functioned as an integrated shadow-measuring system, potentially enabling Early Neolithic communities to mark key calendrical thresholds throughout the year.

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
