November 29th is the anniversary of the birth of C.S. Lewis. In his university lectures on the medieval cosmos, Lewis would sometimes refer to his own birthday, saying: ‘Those born under Jupiter are apt to be cheerful and festive, loud-voiced and red-faced.’ He would then pause and add, ‘It is obvious under which planet I was born!’ – which always produced a laugh.
Lewis did not literally believe in astrology, but he certainly admired the poetical use to which astrological symbolism could be put. ‘The characters of the planets, as conceived by medieval astrology, seem to me to have a permanent value as spiritual symbols,’ he wrote in 1935. In this article I want to show something of what he thought about the stars and planets not only in connection with his own birthday and ‘days’ in general, but also with an immeasurably greater day, the Feast of Christmas, the nativity of Christ.
From time immemorial and right through into the late Middle Ages, there were only seven known planets. Uranus was not discovered till 1781, Neptune in 1845, and Pluto in 1930 (since 2006 it has been classified as a ‘dwarf planet’). A planet is literally a ‘wanderer’. The planets are the wandering stars that take their own individual paths across the sky. All the other celestial bodies are not planets, but stars, either fixed in their own unique positions, like the Pole Star, or forming fixed parts of larger constellations. The seven medieval planets included the Sun and the Moon; the other five were Mercury, Venus, Mars, Jupiter, and Saturn. The Earth was not considered ‘Planet’ Earth, but rather was thought to be the still centre of the turning universe.
It is from the seven medieval planets that we take the names of the days of the week. How Saturday, Sunday, and Monday relate to Saturn, the Sun, and the Moon is pretty obvious. The connection between the other four planets and the other four days of the week is slightly concealed from us who speak English because, for some odd reason lost in the mists of time, we use the Norse names for the relevant planetary deities rather than the Roman names. Thus Tuesday is named for Tiw or Tyr, the Norse equivalent of the Roman god, Mars (think of Martes in Spanish or Mardi in French). Wednesday is named for Woden, the Norse equivalent of the Roman Mercury (Miercoles / Mercredi). Thursday is named for Thor, the Norse equivalent of Jupiter or Jove (Jueves / Jeudi). And Friday is named for Freya or Frigg, the Norse equivalent of Venus (Viernes / Vendredi).
In the course of researching Lewis and the seven heavens for my book, Planet Narnia, I discovered a page of notes (see below) that he scribbled in the end-leaves of one of the volumes of his complete edition of Chaucer. These notes, which Lewis made about Chaucer’s poem, ‘The Knight’s Tale’, from The Canterbury Tales, indicate the interest Lewis took in the poetic use that could be made of planetary symbolism. Lewis admired the way Chaucer not only put the planetary characters into ‘The Knight’s Tale’ as actors in the drama, but also wove the relevant planetary influences into the plot. So, for example, the climax of ‘The Knight’s Tale’ happens on a Tuesday, the day of Mars, an appropriate ending for a story about martial knights.
Lewis’s notes explain how it is that certain days of the week are connected to particular planets. He writes: ‘The first hour of every day belongs to the planet of the day: after that the others follow in downward order from him to the rest; then go on repeating.’
To understand what Lewis means by ‘downward order’, take a look at the diagram below, showing the seven heavens. The planet in the seventh heaven is Saturn. Below Saturn come Jupiter, Mars, the Sun, Venus, Mercury, and the Moon.
Lewis’s notes clarify why Monday follows Sunday in the order of the days of the week, even though the Moon and the Sun are not adjacent in the order of the planets. The Sun, being the eye and mind of the whole universe, was believed to rule the first hour of the first day of the week. After the Sun has laid claim, so to speak, to Sunday by ruling its first hour, it moves aside and allows Venus, the planet immediately underneath in the order of the planets, to rule the second hour of Sunday. Venus then makes way for Mercury to rule the third hour of Sunday, and Mercury then lets the Moon have a go. After the Moon has ruled the fourth hour, there are no planets lower down to take over, so the sequence starts again from the top, with Saturn ruling the fifth hour of Sunday, Jupiter ruling the sixth hour, and Mars ruling the seventh hour. At the eighth hour, it’s the Sun’s turn again. And, as the sequence continues, the Sun rules also the fifteenth hour and the twenty-second hour. With the day drawing to a close, the twenty-third hour of Sunday is ruled by Venus, the twenty-fourth hour by Mercury, and then Sunday’s twenty-fifth hour (as it were) is governed by the Moon, but since each day only has 24 hours, we find ourselves in a new day, whose first hour is Lunar, – hence we call it Moonday. And that, in a nutshell, is why Monday follows Sunday!
Back to the date of Lewis’s birthday and his being born under Jupiter: we are all familiar with the idea of being ‘born under’ a planet. We tend to think of this mostly in connection with the twelve houses or ‘signs’ of the zodiac, as they correspond (roughly) to the twelve months of the year. If you are born in late November, like C.S. Lewis, that puts you in the house of Sagittarius, whose sign is a centaur aiming a bow and arrow. The planet responsible for ‘ruling’ that zodiacal house, according to astrological tradition, is Jupiter. So Lewis was indeed ‘born under’ Jupiter, as he said he was, at least as regards the month of his birth.
As for the day on which he was born: 29th November fell on a Tuesday in 1898, so he was born under Mars as well as under Jupiter. I do not know the hour in which he was born on that Tuesday, but one supposes it to have been a ‘jovial’ hour. Lewis was a hearty, rubicund man who had a love of Jupiter (or Jove) throughout his life. He inherited these qualities from his father, for Albert Lewis was ‘often the most jovial and companionable of parents’, according to Surprised by Joy.
Lewis once declared that, if he were to marry anyone, it would be the poet Ruth Pitter (this was before he was surprised by Joy Davidman!). He wrote to her in 1954 remarking on her name: ‘I always thought that the Pitters (dies-piter and all that) descended from Jove through Aeneas and Brute.’ The name Jupiter derives from dies-piter, which literally means ‘shining father’, as Lewis would have known from (among other sources) Edwyn Bevan’s Symbolism and Belief, a book he rated highly.
Brute, or Brut, the first king of Britain in mythical history, was the son of Aeneas Silvius, grandson of Ascanius and great-grandson of Aeneas of Troy. In another letter of 1954, Lewis offers a little more detail about this mythical British or Celtic line ‘that goes back through the Tudors to Cadwallader and thence to Arthur, Uther, Cassibelan, Lear, Lud, Brut, Aeneas, Jupiter.’ It is amusing to find Lewis, the self-styled Jovial man, toying with the idea of marrying into Jupiter’s family by taking Ruth Pitter as his wife. And it is intriguing to observe that Lewis gives to the heroine of That Hideous Strength, Jane Studdock, the surname ‘Tudor’ as her maiden name. Jane and her husband Mark (a suitably Martial moniker) are to become the parents of a son who will perpetuate Jupiter’s line in modern-day England.
How apt, incidentally, that Lewis’s favourite Oxford pub, the Eagle & Child, home to so many meetings of the Inklings, was named for an episode in the life of Zeus, the forerunner in Greek mythology of the Roman god, Jupiter. Zeus fell in love with the beautiful child, Ganymede, and sent an eagle to snatch him up to Mount Olympus where he could serve as his royal cup-bearer.
Those who knew C.S. Lewis have often noted his joviality, though not always with a clear recognition of the significance the term had for him in his personal lexicon. Paul Piehler remembers ‘a plumpish, red-faced Ulsterman with a confident, jovial Ulster rasp to his voice’. Peter Milward recalls ‘a burly, red-faced, jovial man’. John Lawlor relates how Lewis’s ‘determined and even aggressive joviality was all on the surface: within was a settled contentment’. Peter Bayley describes him as ‘Jove-like, imperious, certain, absolute’. Richard Ladborough says he was ‘frequently jovial’. W.R. Fryer speaks of his ‘jovial maleness’. Peter Philip opines that ‘his manner was jovial when he was in a good mood, which I must say was most of the time’. Pat Wallsgrove likens Lewis to ‘a jovial farmer’. Claude Rawson writes that his nickname, ‘Jack’, was ‘well suited to his jovial “beer and Beowulf” image’. Nevill Coghill recalls that, although Lewis was formidable, ‘this was softened by joviality’. Douglas Gresham remembers his step-father as ‘jovial’. The title of Chesterton’s novel, The Man Who Was Thursday, might have been coined as a description of C.S. Lewis, notwithstanding his Tuesday nativity!
But though so many people use the word ‘jovial’ of the man, only George Watson, his Cambridge colleague, explicitly recognizes how important the planetary derivation was for Lewis himself: ‘His own humour was sanguine, its presiding deity Jove, and . . . he knew that it was’ (Watson, Critical Essays on C.S. Lewis, 1992, p3). Peter Milward goes further, making a link to Lewis’s fiction. Having emphasized Lewis’s ‘sturdily jovial manner’, Milward notes an important connection: ‘he was indeed a . . . jovial man; and these qualities of his I later recognized . . . in his character of the kingly animal, Aslan.’
Aslan, Narnia’s Christ figure, brings us to Christmas and the birth of the infant Jesus. In early January 1953, Lewis wrote to Ruth Pitter remarking on what he had seen in the night-sky during the recent Christmas: ‘It was beautiful, on two or three successive nights about the Holy Time, to see Venus and Jove blazing at one another, once with the Moon right between them: Majesty and Love linked by Virginity – what could be more appropriate?’ Venus signifies love, of course, and the Moon virginity. Jupiter signifies majesty or kingliness and, as such, was a very suitable symbol for Christ, the ‘king of kings’ (Revelation 19:16).
In attempting to read the significance of the Christmas stars, Lewis was modeling himself on the magi, the wise men who followed the star from the east and who came to Herod asking, ‘Where is he that has been born King of the Jews?’ (Matthew 2:2). There is a right and proper use of astrology, if it leads to the worship of Christ. That the stars speak of Christ is only to be expected, for, in the words of Lewis’s favourite psalm, ‘The heavens are telling the glory of God’ (Psalm 19:1).
Lewis was alert to the royal and imperial implications of Christ’s nativity. Writing about Psalm 110 in his only full-length work of scriptural commentary, Reflections on the Psalms (1958), Lewis notes that this psalm is appointed to be read on Christmas Day in the order of readings given by the Anglican Prayer Book. He remarks:
We may at first be surprised by this. There is nothing in [Psalm 110] about peace and goodwill, nothing remotely suggestive of the stable at Bethlehem. It seems to have been originally either a coronation ode for a new king, promising conquest and empire, or a poem addressed to some king on the eve of war, promising victory. It is full of threats. The “rod” of the king’s power is to go forth from Jerusalem, foreign kings are to be wounded, battle fields to be covered with carnage, skulls cracked. The note is not “Peace and goodwill” but “Beware. He’s coming”. Two things attach it to Christ with an authority far beyond that of the Prayer Book. The first of course is that He Himself did so; He is the “lord” whom “David” calls “my Lord”. The second is the reference to Melchizedek.
Lewis then proceeds to give a detailed disquisition on Melchizedek, the numinous priest-king mentioned in the Book of Genesis (14:18-19). Melchizedek becomes, in Psalm 110, a spiritual ancestor of the Davidic king. The psalmist says of the king, ‘thou art a priest forever in the order of Melchizedek’, a description which is taken up in the New Testament in the Epistle to the Hebrews and applied repeatedly to Jesus Christ (Hebrews 5:6; 6:20; 7:11; 7:17; 7:21).
There is one interesting fact about Melchizedek that Lewis does not disclose in his Reflections on the Psalms, though he undoubtedly knew of it, and it provides another reason for regarding this Christmas psalm as Jovial in its symbolism: the Hebrew word Melchizedek means both ‘my king is righteousness’ and ‘my king is Jupiter’. (For more details on this fascinating link, see the helpful article here.)
Jesus Christ, the king of kings and lord of lords, the divine Word by whom all things were made, spoke the planet Jupiter into being on the fourth day of creation (Genesis 1:14-19). Lewis in his commentary on the psalms is not, of course, arguing, or even suggesting, that Jesus was actually ‘born under Jupiter’, as he jokingly told his university lecture audiences that he himself had been. But from all that we have seen of his interest in the planets and his love of Jove in particular, I am sure he would have considered the idea highly appropriate.
