I couldn't find anything for an Obelisk.. do you know what heritage it is?
Mars -
The god of war, and one of the most prominent and worshipped gods. In early Roman history he was a god of spring, growth in nature, and fertility, and the protector of cattle. Mars is also mentioned as a chthonic god (earth-god) and this could explain why he became a god of death and finally a god of war. He is the son of Jupiter and Juno. According to some sources, Mars is the father of Romulus and Remus by the Vestal Ilia (Rhea Silvia). Because he was the father of these legendary founders of Rome, and thus of the Roman people, the Romans styled themselves 'sons of Mars'.
His main sanctuaries where the temple on the Capitol, which he shared with Jupiter and Quirinus, the temple of Mars Gradivus ("he who precedes the army in battle") where the Roman army gathered before they went to war, and the temple of Mars Ultor ("the avenger"), located on the Forum Augustus. The Campus Martius ("field of Mars"), situated beyond the city walls, was also dedicated to him. Here the army was drilled and athletes were trained. In the Regia on the Forum Romanum, the 'hastae Martiae' ("lances of Mars") were kept. When these lances 'moved', it was seen as a portent of war. The warlord who was to lead the army into battle had to move the lances while saying 'Mars vigila' ("Mars awaken"). As Mars Gradivus, the god preceded the army and led them to victory.
He had several festivals in his honor. On March 1, the Feriae Marti was celebrated. The Armilustrium was held on October 19, and on this day the weapons of the soldiers were ritually purified and stored for winter. Every five years the Suovetaurilia was held. During these fertility and cleansing rites, a pig (sus), a sheep (ovis) and bull (taurus) were sacrificed. The Equirria were on February 27 and March 14, on which horse races were held. The Quinquatrus was on March 19 and the Tubilustrium on March 23, on which weapons and war-trumpets were cleansed. The priests of Mars, who also served Quirinus, were called the Salii ("jumpers"), derived from the procession through the streets of the city which they completed by jumping the entire way and singing the Carmen Saliare. Mars' own priest was called the flamen Martialis.
Mars is portrayed as a warrior in full battle armor, wearing a crested helmet and bearing a shield. His sacred animals are the wolf and the woodpecker, and he is accompanied by Fuga and Timor, the personifications of flight and fear. The month March (Martius) is named after him (wars were often started or renewed in spring). His Greek equivalent is the god Ares.
Ra -
Cross-referenced to Re -
The most important of the Egyptian gods, the personification of the (midday) sun. According to the Heliopolitan cosmology he created himself from a mound that arose from the primeval waters of Nun or out of a primordial lotus flower. He then created Shu (air) and Tefnut (moisture), who in turn engendered the earth-god Geb and the sky-goddess Nut. Re was said to have created humankind from his own tears and the gods Hu and Sia from blood drawn from his own penis.
The sun itself was taken to be either his body or his eye (the 'Eye of Re'). The center of his cult was from the very beginning in Heliopolis, where he was also venerated in the forms of Atum (the setting sun) and Khepri (the rising sun) and, in connection to the morning sun, as Re-Harachte. As Re-Atum he is the creator who gives light and warmth and thus growth. Re was often combined with other deities to enhance the prestige of the latter, as in Re-Atum or Amun-Re.
It was said that Re traveled each day in his solar barque through the sky, starting in the morning. At night, Re journeyed through the underworld in another barque. And each night, the monster Apep would try to prevent the sun-god from emerging again; the eternal battle between light and darkness. The gods Seth and Mehen accompanied him and were often depicted defending Re's barque. Others believed that Re could be found at night in the underworld, consoling and giving support to the dead. Re is also the god of the pharaohs and since the fourth dynasty the Egyptian kings styled themselves 'sons of Re'. After death, the monarch was said to ascend into the sky to join the entourage of Re.
In Heliopolis the Benu or Phoenix (sacred heron) and the oracular Mnevis (bull) were venerated as manifestations of the sun-god. Here the kings also built temples for Re, which were important institutions in the field of ideology. Re was usually portrayed as a man with the head of a falcon, crowned with the sun disc encircled by the uraeus.
AND in case you mean Amun-Ra -
A combination of Amun and Re from later Egyptian mythology, also called Amon-Ra. The Theban god Amun became the national god of Egypt under this name.
