Rakib-El is a god who appears in Phoenician and Aramaic inscriptions. Panammuwa II died unexpectedly while in Damascus. However, his son the king Bar-Rakib was not a native of Damascus but rather the ruler of Sam'al it is unknown if other rules of Sam'al used similar language. In Greek mythology, Heracles (son of Zeus) and many other figures were considered to be sons of gods through union with mortal women. From around 360 BC onwards Alexander the Great may have implied he was a demigod by using the title "Son of Ammon–Zeus". In 42 BC, Julius Caesar was formally deified as "the divine Julius" ("divus Iulius") after his assassination. His adopted son, Octavian (better known as Augustus, a title given to him 15 years later, in 27 BC) thus became known as "divi Iuli filius" (son of the divine Julius) or simply "divi filius" (son of the god). As a daring and unprecedented move, Augustus used this title to advance his political position in the Second Triumvirate, finally overcoming all rivals for power within the Roman state. The word applied to Julius Caesar as deified was "divus", not the distinct word "deus". Thus Augustus called himself "Divi filius", and not "Dei filius". The line between been god and god-like was at times less than clear to the population at large, and Augustus seems to have been aware of the necessity of keeping the ambiguity. As a purely semantic mechanism, and to maintain ambiguity, the court of Augustus sustained the concept that any worship given to an emperor was paid to the "position of emperor" rather than the person of the emperor. However, the subtle semantic distinction was lost outside Rome, where Augustus began to be worshiped as a deity. The inscription DF thus came to be used for Augustus, at times unclear which meaning was intended. The assumption of the title "Divi filius" by Augustus meshed with a larger campaign by him to exercise the power of his image. Official portraits of Augustus made even towards the end of his life continued to portray him as a handsome youth, implying that miraculously, he never aged. Given that few people had ever seen the emperor, these images sent a distinct message. Later, Tiberius (emperor from 14–37 AD) came to be accepted as the son of "divus Augustus" and Hadrian as the son of "divus Trajan".
