What was the dark-feathered god of desire? What secrets that masterwork reveals about the rogue artist

The young boy cries out as his head is forcefully held, a massive digit pressing into his cheek as his father's powerful hand holds him by the neck. That moment from Abraham's Sacrifice appears in the Uffizi Gallery, evoking distress through the artist's chilling rendition of the suffering child from the biblical narrative. The painting seems as if the patriarch, commanded by the Divine to kill his son, could break his neck with a solitary twist. Yet the father's chosen approach involves the metallic grey knife he grips in his other hand, ready to cut Isaac's throat. A certain element remains – whoever modeled as the sacrifice for this breathtaking piece demonstrated remarkable acting skill. Within exists not just dread, surprise and begging in his shadowed eyes but additionally deep grief that a protector could abandon him so utterly.

He took a familiar biblical tale and transformed it so vibrant and visceral that its horrors seemed to happen directly in view of you

Viewing before the artwork, viewers recognize this as a real face, an accurate record of a adolescent subject, because the same boy – recognizable by his disheveled hair and nearly black pupils – appears in several additional paintings by Caravaggio. In each instance, that highly expressive face dominates the composition. In John the Baptist, he gazes playfully from the darkness while holding a ram. In Amor Vincit Omnia, he smirks with a toughness learned on Rome's alleys, his dark feathery wings demonic, a unclothed adolescent running riot in a well-to-do residence.

Amor Vincit Omnia, presently displayed at a British museum, constitutes one of the most discomfiting masterpieces ever painted. Observers feel completely unsettled gazing at it. Cupid, whose darts inspire people with frequently painful longing, is portrayed as a extremely real, brightly lit nude form, standing over overturned items that include musical devices, a music manuscript, plate armor and an builder's T-square. This heap of items echoes, intentionally, the mathematical and construction equipment strewn across the ground in Albrecht DΓΌrer's engraving Melancholy – except here, the melancholic mess is created by this grinning Cupid and the mayhem he can release.

"Love sees not with the vision, but with the soul, / And thus is winged Cupid painted blind," wrote Shakespeare, shortly before this painting was created around 1601. But the painter's god is not unseeing. He gazes directly at you. That countenance – ironic and ruddy-cheeked, looking with bold confidence as he poses naked – is the identical one that shrieks in fear in Abraham's Test.

As Michelangelo Merisi da Caravaggio created his multiple images of the same distinctive-looking kid in Rome at the dawn of the seventeenth century, he was the highly celebrated sacred artist in a city ignited by Catholic revival. Abraham's Offering reveals why he was sought to adorn sanctuaries: he could take a biblical narrative that had been portrayed many occasions previously and make it so fresh, so raw and visceral that the terror appeared to be occurring immediately in front of the spectator.

Yet there existed a different aspect to Caravaggio, apparent as soon as he came in Rome in the cold season that concluded the sixteenth century, as a painter in his initial 20s with no teacher or supporter in the urban center, only talent and audacity. Most of the paintings with which he caught the sacred metropolis's eye were anything but devout. What could be the absolute first hangs in the UK's art museum. A young man parts his crimson mouth in a yell of pain: while stretching out his dirty fingers for a cherry, he has instead been attacked. Youth Bitten by a Reptile is sensuality amid squalor: viewers can discern the painter's dismal room mirrored in the cloudy liquid of the glass container.

The adolescent wears a pink blossom in his hair – a symbol of the sex commerce in early modern painting. Venetian artists such as Tiziano and Jacopo Palma depicted courtesans holding flowers and, in a painting destroyed in the second world war but known through images, Caravaggio portrayed a famous woman courtesan, holding a bouquet to her bosom. The message of all these botanical signifiers is obvious: sex for sale.

What are we to make of the artist's sensual portrayals of youths – and of one boy in specific? It is a inquiry that has divided his interpreters since he achieved mega-fame in the twentieth century. The complicated past truth is that the artist was neither the queer hero that, for instance, Derek Jarman put on screen in his twentieth-century film about the artist, nor so completely devout that, as some art scholars improbably claim, his Youth Holding Fruit is in fact a likeness of Jesus.

His initial works do make explicit erotic implications, or including offers. It's as if Caravaggio, then a destitute young creator, identified with the city's prostitutes, offering himself to live. In the Uffizi, with this thought in mind, viewers might look to another early creation, the 1596 masterpiece Bacchus, in which the god of wine gazes calmly at you as he begins to undo the dark sash of his garment.

A several annums after Bacchus, what could have driven the artist to paint Victorious Cupid for the artistic patron the nobleman, when he was at last becoming nearly established with prestigious ecclesiastical projects? This profane pagan deity resurrects the sexual challenges of his early works but in a more powerful, uneasy manner. Fifty years later, its secret seemed obvious: it was a portrait of Caravaggio's lover. A British visitor viewed Victorious Cupid in about 1649 and was informed its figure has "the body & face of [Caravaggio's|his] owne boy or servant that slept with him". The name of this adolescent was Francesco.

The artist had been dead for about forty years when this story was documented.
