BCE). Thus, by this time, cattle religion (e.g., myths, rituals) and cultural distinctions between genders (e.g., men associated with bulls, violence, hunting, and dogs as well as burials at monumental funerary sites; women associated with cows, birth, nursing, and possibly the afterlife) had developed. Preceded by assumed earlier sites in the Eastern Sahara, tumuli with megalithic monuments developed as early as 4700 BCE in the Saharan region of Niger. These megalithic monuments in the Saharan region of Niger and the Eastern Sahara may have served as antecedents for the mastabas and pyramids of ancient Egypt. During Predynastic Egypt, tumuli were present at various locations (e.g., Naqada, Helwan). Between 7500 BP and 7400 BP, amid the Late Pastoral Neolithic, religious ceremony and ceremonial burials, with megaliths, may have served as a cultural precedent for the latter religious reverence of the goddess Hathor during the dynastic period of ancient Egypt. Early architecture Probably the most famous class of structure in all Africa, the Pyramids of Egypt remain one of the world's greatest early architectural achievements, regardless of practicality and origins in a funerary context. Egyptian architectural traditions also favored the building of vast temple complexes. Little is known of ancient architecture south and west of the Sahara. Harder to date than the pyramids are the monoliths around the Cross River, which have geometric or human designs. The vast number of Senegambian stone circles is also evidence of an emerging architecture. North Africa Likely part of Copper Age and Bronze Age cultural traditions of megalith-building, megaliths (e.g., dolmens) were constructed in Mediterranean North Africa. Algeria Garamantes Some of the earliest evidence of original Amazigh (Berber) culture in North Africa has been found in the highlands of the Sahara and dates from the second millennium BC, when the region was much less arid than it is today and when the Amazigh population was most likely in the process of spreading across North Africa. One of the earliest groups for which there are historical records are the Garamantes, who were later mentioned by Herodotus. Numerous archaeological sites associated with them have been found in the Fezzan (in present-day Libya), attesting to the existence of small villages, towns, and tombs. At least one settlement dates from as early as 1000 BC. The structures were initially built in dry stone, but around the middle of the millennium (c. 500 BC) they began to be built with mudbrick
