to the hieroglyphics on the tomb, it was detected that the tomb belongs to a tradesman named Tjit. Piacentini commented “It's a very important discovery because we have added something to the history of Aswan that was missing. We knew about tombs and necropoli dating back to the second and third millennium, but we didn't know where the people who lived in the last part of the Pharaonic era were. Aswan, on the southern border of Egypt, was also a very important trading city”. Stan Hendrick, John Coleman Darnell and Maria Gatto in 2012 excavated petroglyphic engravings from Nag el-Hamdulab in Aswan which featured representations of a boat procession, solar symbolism and the earliest depiction of the White Crown with an estimated dating range between 3200BC and 3100BC. In February 2021, archaeologists from the Egyptian Ministry of Antiquities announced significant discoveries at an archaeological site called Shiha Fort in Aswan, namely a Ptolemaic period temple, a Roman fort, an early Coptic church and an inscription in hieratic script. According to Mostafa Waziri, the crumbling temple was decorated with palm leaf carvings and an incomplete sandstone panel that described a Roman emperor. Researcher Abdel Badie states more generally that the church contained ovens used to bake pottery, four rooms, a long hall, stairs, and stone tiles. Geography Northern Tropic boundary The latitude of the city that would become Aswan – located at 24° 5′ 23″ – was an object of great interest to the ancient geographers and mathematicians. They believed that it was seated immediately under the tropic, and that on the day of the summer solstice, a vertically positioned staff cast no shadow. They noted that the sun's disc was reflected in a deep well (or pit) at noon. This statement is only approximately correct; at the summer solstice, the shadow was only of the staff, and so could scarcely be discerned, and the northern limb of the Sun's disc would be nearly vertical. More than 2200 years ago, Greek polymath Eratosthenes used this information to calculate earth's circumference. Climate Aswan has a hot desert climate (Köppen climate classification BWh) like the rest of Egypt. Aswan and Luxor have the hottest summer days of any city in Egypt. Aswan is one of the hottest, sunniest and driest cities in the world. Average high temperatures are consistently above during summer (June, July, August and also September) while average low temperatures remain
