THE STAR OF BETHLEHEM, A COMET IN 5 BC AND THE DATE OF CHRIST’S BIRTH

The star of Bethlehem has been considered either to be mythical or a miraculous object beyond the bounds of scientific explanation or a real astronomical phenomenon.2 The question of whether a celestial phenomenon reported in ancient literature in an historical context was a real astronomical object is one which occurs quite frequently. In all such cases it seems best to consider as a working hypothesis that the report is correct and to investigate whether any astronomical phenomenon exists which fits the report. Thus, tentatively, we take seriously the references in Matthew’s gospel and in other ancient literature to the star of Bethlehem which is stated to have appeared near the time of the birth of Christ. If an astronomical object can be identified with the characteristics described in Matthew and other ancient manuscripts, this information may throw light on the long standing problem of the date of the Nativity. In AD 525 a Roman scholar and monk, Dionysius Exiguus, fixed the AD origin of our present calendar (Anno Domini = in the year of our Lord) so that Jesus was circumcised in the year AD 1 on 1 January (8 days, counting inclusively, after his birth on 25 December the previous year). More recently dates ranging from  20 BC to AD 10 have been given for the year of the Nativity.3 Concerning the day, although 25 December is firmly fixed in our calendar, this is unlikely if the arguments in the present paper are accepted. In this article we consider a combination of astronomical and historical evidence which may be used to identify the star of Bethlehem and to determine the date of the Nativity

The earliest known account of the star of Bethlehem is in Matthew 2:1-12. Most scholars accept that the final text of this gospel may have been composed in about AD 80 from sources written in earlier times. Presumably one of these sources recorded the star of Bethlehem and the visit of the Magi. The account in Matthew describes how the Magi saw a star which they believed heralded the birth of the Messiah–king of the Jews. They travelled to Jerusalem and informed King Herod of the time when the star appeared, which indicates that the star was not a customary sight. The advisers of Herod told the Magi that, according to the prophesy of Micah, the Messiah should be born in Bethlehem, so the Magi journeyed there. The star moved before them and ‘stood over’ Bethlehem. The Magi found the place where the child was and presented him with gifts.

 The Magi The tradition that the Magi were kings dates from the sixth century AD, . According to Herodotus,4 Magi existed in Persia in the sixth century BC, they were a priestly group among the Medes who performed religious ceremonies and interpreted signs and portents. Persia (now Iran) conquered neighbouring Mesopotamia (now Iraq) and from the fourth century BC onwards Magi were increasingly associated with astronomy and astrology, the observation and the ‘interpretation’ of the stars being  closely related in ancient times and Babylon (in Mesopotamia) became the centre of ancient astronomy and astrology. In about 586 BC the Babylonians sacked Jerusalem and took the Jews into Exile. From the time of the Exile onwards Babylon contained a strong Jewish colony, and the knowledge of the Jewish prophecies of a Saviour–King, the Messiah, may have been well-known to the Babylonians and to the Magi. In the Hellenistic age some of the Magi left Babylon and travelled to neighbouring countries to teach and practise astronomy/astrology, which was a core educational subject in the ancient world.5 Thus the first century AD Jewish scholar Philo of Alexandria stated that the student of astronomy perceived ‘timely signs of coming events’ since ‘the stars were made for signs’.6 There is a strong tradition that the Magi who visited Jesus came from Arabia (now Saudi Arabia), which lies between Mesopotamia and Palestine. Thus in about AD 160 Justin Martyr wrote ‘Magi from Arabia came to him [Herod]’ and in about AD 96 Clement of Rome7 associated frankincense and myrrh, two of the gifts of the Magi, with ‘the East, that is the districts near Arabia’. We conclude that the Magi who saw the star of Bethlehem were astronomers/astrologers, who may have been familiar with the Jewish prophecies of a Saviour–King, and who probably came from Arabia or Mesopotamia, countries to the east of Palestine. Matthew 2:1 simply states ‘Magi from the East arrived in Jerusalem’. It is important to realise that there are many references in ancient literature to Magi visiting kings and emperors in other countries. For example, Tiridates, the King of Armenia, led a procession of Magi to pay homage to Nero in Rome in AD 66.8 Thus a visit by the Magi to pay homage to Jesus, the new King of the Jews, would not have appeared as particularly unusual to readers of Matthew’s gospel. However, the Magi must have had an
