This happiness sadly ended when Zelda was admitted to the Les Rives de Prangins Clinic in Switzerland for serious mental ill health. At this time, Fitzgerald was contending with alcohol addiction, and the pair’s afflictions made their written exchanges far more scornful.

However, in viewing their earlier letters, we catch a glimpse of a relationship that was joyful:

“Why is there happiness and comfort and excitement where you are and nowhere else in the world?” Fitzgerald pens.

“Your photograph is all I have,” Zelda replies, “it is with me from the morning when I wake up with a frantic half dream about you to the last moment when I think of you and of death at night.”

Zelda wrote other missives, which provide warm details of her feelings towards Fitzgerald:

“I look down the tracks and see you coming – and out of every haze & mist your darling rumpled trousers are hurrying to me – Without you, dearest dearest I couldn’t see or hear or feel or think – or live – I love you so and I’m never in all our lives going to let us be apart another night. It’s like begging for mercy of a storm or killing Beauty or growing old, without you. I want to kiss you so – and in the back where your dear hair starts and your chest – I love you – and I can’t tell you how much – To think that I’ll die without your knowing – Goofo, you’ve got to try to feel how much I do – how inanimate I am when you’re gone – I can’t even hate these damnable people – Nobodys got any right to live but us – and they’re dirtying up our world and I can’t hate them because I want you so – Come Quick – Come Quick to me – I could never do without you if you hated me and were covered with sores like a leper – if you ran away with another woman and starved me and beat me – I still would want you I know – Lover, Lover, Darling – Your Wife.”

And it wasn’t only creatives who recorded the anguish of missing loved ones on paper. Napoleon Bonaparte, whilst claiming his place in history as a ruthless military leader, appears to have been far more tender in his personal life.

In a letter he wrote to his first wife, Joséphine, translated from French by Henry Foljambe Hall in 1901, he says:

“Ever since I left you, I have been sad. I am only happy when by your side. Ceaselessly I recall your kisses, your tears, your enchanting jealousy; and the charms of the incomparable Joséphine keep constantly alight a bright and burning flame in my heart and senses. When, free from every worry, from all business, shall I spend all my moments by your side, to have nothing to do but to love you, and to prove it to you? I shall send your horse, but I am hoping that you will soon be able to rejoin me. I thought I loved you some days ago; but, since I saw you, I feel that I love you even a thousand times more.”

Unearth your poetic side

British writer Oscar Wilde fell hard for Oxford undergraduate Lord Alfred Douglas in June 1891, who he was introduced to by a friend, Lionel Johnson.

Wilde and ‘Bosie’, as he referred to him, were very different, though. Whilst Wilde was non-confrontational, Douglas was fierier. But with fire came passion, a presence made clear by the writers in their letters:

“My Own Boy

“Your sonnet is quite lovely, and it is a marvel that those red-roseleaf lips of yours should be made no less for the madness of music and song than for the madness of kissing. Your slim gilt soul walks between passion and poetry. I know Hyacinthus, whom Apollo loved so madly, was you in Greek days. Why are you alone in London, and when do you go to Salisbury? Do go there to cool your hands in the grey twilight of Gothic things, and come here whenever you like. It is a lovely place and lacks only you; but go to Salisbury first.

“Always, with undying love,

“Yours, Oscar”

In HM Prison Reading, following his sentence, Wilde wrote a 50,000-word letter to Douglas, which became known as De Profundis (From the Depths). In the first half of the letter, he discusses the two’s relationship and, in the second, a spiritual awakening he experienced during his imprisonment.

His exchanges with Douglas prove that there are no limitations when writing a letter to a loved one, especially for the more poetic amongst us.

Reflect on the past

Musicians Johnny Cash and June Carter Cash were married for over 30 years. The two met when still married to other people, a difficult situation that inspired June’s cowriting of the song Ring of Fire with Merle Kilgore.

During their marriage, the couple overcame the turbulence fame, and life, can often bring – including Johnny’s addictions to drugs and alcohol. Their letters show the devotion that allowed them to survive the difficulties they faced. In a letter, Johnny reflects on their past:

“Happy Birthday Princess,

“We get old and get used to each other. We think alike.

“We read each other’s minds. We know what the other wants without asking. Sometimes we irritate each other a little bit. Maybe sometimes take each other for granted.

“But once in awhile, like today, I meditate on it and realize how lucky I am to share my life with the greatest woman I ever met. You still fascinate and inspire me.”

Make promises for the future

King Henry VIII’s marriage to Anne Boleyn might have been severed, quite literally, but his written professions prior to their union were not short of promises. Anne was not satisfied with being a mistress of the Tudor king; she wanted to be his wife.

And, for the woman he dissolved the Catholic church for, it might come as a surprise to discover that Henry was willing to do plenty more:

“But if you please to do the office of a true loyal mistress and friend, and to give up yourself body and heart to me, who will be, and have been, your most loyal servant, (if your rigour does not forbid me) I promise you that not only the name shall be given you, but also that I will take you for my only mistress, casting off all others besides you out of my thoughts and affections, and serve you only. I beseech you to give an entire answer to this my rude letter, that I may know on what and how far I may depend. And if it does not please you to answer me in writing, appoint some place where I may have it by word of mouth, and I will go thither with all my heart. No more, for fear of tiring you.”

How to end a love letter

Look no further than Prince Albert’s sign off…

The marriage between Queen Victoria and Prince Albert has been reinvented over and over on the screen. The couple’s relationship is said to have been bursting with passion, and Victoria delivered nine children during their time together.

Before this union was cut tragically short by Albert’s death, plunging Victoria into life-long mourning, their letters demonstrate the love they shared for each other:

“Dearest deeply loved Victoria, I need not tell you that since we left, all my thoughts have been with you at Windsor, and that your image fills my whole soul. Even in my dreams I never imagined that I should find so much love on earth. How that moment shines for me still when I was close to you, with your hand in mine. Those days flew by so quickly, but our separation will fly equally so. Ernest wishes me to say a thousand nice things to you. With promises of unchanging love and devotion, your ever true Albert.”
