The dark origins of Valentine's Day.

The holiday began as a feast to celebrate the decapitation of a third-century Christian martyr, or perhaps two. So how did it become all about love?

Some believe Valentine's Day evolved from the Roman holiday Lupercalia

The festival, which took place in mid-February, featured Roman priests sacrificing a goat and using its hide to lightly slap women and the land, believing it would bring fertility. Some believe that the Catholic Church repurposed the pagan holiday as a Christian one by attaching it to a saint, but scholars are not certain that this is true.

Poet Geoffrey Chaucer inspired the modern, romantic version of Valentine's Day

In the 1380s, the "Canterbury Tales" author wrote "The Parliament of Fowls," a 700-line poem about birds that choose their mates on St. Valentine's Day. The poem argued that romantic love—for fowls and humans alike—was an ideal, and linked the holiday with that sentiment.

In the 20th century, Valentine's Day became more commercialized

Historian Elizabeth Nelson notes that companies sought "to turn holidays into opportunities for selling things from candy to flowers to magazine advertisements" in the 1900s. Hallmark, founded in 1911, pushed the holiday toward elementary students, who aimed to collect cards from as many classmates as possible.

'Roses are red, violets are blue' has a long, twisting history

The earliest known use of the phrase, a stock romance form used in greeting cards, is in Edmund Spenser's "The Faery Queen" from 1590 (excerpt below). By 1785, Joseph Ritson updated the verse and connected it to Valentine's Day, creating a cliché that's still used today.

19th-century 'vinegar valentines' sometimes mocked recipients

In Victorian England, cards were sent to paramours and crushes, but they were also sometimes sent to people the sender disliked and would belittle them for their occupations or appearances. It was also expected that anyone who received a Valentine's Day card would send one in return, so there was a subgenre of responses, including rejections for unwanted suitors.

Reforms reducing postage rates helped popularize Valentine's Day cards

In 1845, Congress voted to slash postage rates, paving the way for larger swaths of the American public to send and receive mail.

Advertisers emphasized Cupid's childlike qualities to appeal to a younger demographic

Cupid is the Roman god of desire, and was often depicted in ancient mythology as both childlike and violent. In the 1800s, however, American advertisers eager to appeal to a younger demographic leaned into the less threatening versioning, portraying him as a cherubic child.

A scholarly analysis of romance's enduring popularity

Diane Winston, a media scholar at the University of Southern California, argues that romance novels have remained popular because they've historically offered women shame-free ways to explore their identities and sexualities. She notes that's even more true today, with contemporary romance novels, from romantasy bestsellers to "Heated Rivalry," more willingly explore social dynamics.

Mardi Gras blends pagan celebrations with Christian traditions

The holiday has its roots in pagan celebrations, like ancient Rome's Saturnalian and Lupercalian festivals, which celebrated spring and fertility.

Around the world, this holiday season is called Carnival, though the New Orleans version is usually called Mardi Gras.

January is named after Janus, the Roman god of transitions

In 46 BCE, Julius Caesar introduced the Julian calendar, which established Jan. 1 as the beginning of the new year. The month was named after Janus, the Roman god of transitions, who had two faces—one looking back at the past, the other forward to the future.

The petty ancient Roman poet Gaius Valerius Catullus

Classics with a capital "C" probably doesn't bring to mind erotically charged diss poetry. Gaius Valerius Catullus would like to change that. Instead of mythical epics, Catullus wrote poetry about his personal life as part of the 1st century BCE's "new wave" of Roman poets embracing the lyrical and everyday. The focus of his poetic work ranges from serenades to spiteful insults.

What is Good Friday, and why is it called 'good'?

Good Friday commemorates the crucifixion of Jesus, the darkest moment in the Christian story (which makes the name a genuine puzzle). Typical explanations say "good" once meant "holy" or "sacred," while other traditions dub it "sorrowful Friday." Christians observe rather than celebrate the day, with services, fasting, and quiet. It's always two days before Easter, sitting between Maundy (or Holy) Thursday and Easter.

A medievalist explains how romantic love emerged as a cultural concept

Many long-form stories written in English were originally considered "romances," a term derived from the Old French word for "the speech of the people." But changes in medieval culture, triggered by a number of 12th-century church reforms, led to a new interest in what we now consider romantic love, including a new view of marriage as a pursuit of love rather than a transaction. Those new perspectives were then reflected in the period's popular stories, including stories in Chaucer's "Canterbury Tales."

'Coral Castle,' Florida's self-built monument to a lost valentine

Early Christians viewed the Resurrection as a political claim about authority

Titles like "Son of God," "Lord," and "Savior" were in active circulation as official imperial titles at the time, stamped on Roman coins and carved into public inscriptions about Caesar.

The story of Sporus, the castrated boy who married Emperor Nero
