What was the dark-feathered god of love? What insights that masterwork uncovers about the rebellious genius

The youthful lad screams while his skull is firmly held, a large digit digging into his face as his parent's mighty palm grasps him by the neck. That moment from The Sacrifice of Isaac appears in the Uffizi Gallery, evoking unease through Caravaggio's harrowing rendition of the tormented child from the scriptural narrative. It seems as if Abraham, instructed by God to kill his offspring, could break his neck with a single turn. Yet Abraham's preferred approach involves the metallic grey knife he holds in his remaining palm, ready to slit Isaac's neck. A certain aspect stands out – whoever modeled as Isaac for this astonishing work demonstrated extraordinary expressive skill. There exists not just fear, shock and begging in his shadowed gaze but additionally deep sorrow that a protector could betray him so completely.

He adopted a familiar scriptural story and made it so fresh and raw that its terrors appeared to happen directly in view of you

Standing in front of the artwork, observers identify this as a real countenance, an accurate record of a young model, because the identical youth – identifiable by his disheveled locks and almost dark eyes – appears in two additional paintings by Caravaggio. In every case, that highly emotional visage commands the scene. In Youth With a Ram, he gazes playfully from the darkness while embracing a lamb. In Victorious Cupid, he grins with a toughness learned on the city's streets, his black plumed appendages sinister, a naked child creating riot in a affluent residence.

Victorious Cupid, presently exhibited at a British gallery, constitutes one of the most embarrassing masterpieces ever painted. Viewers feel totally disoriented gazing at it. Cupid, whose arrows inspire people with frequently agonizing desire, is shown as a extremely tangible, vividly lit unclothed figure, standing over toppled-over objects that comprise stringed devices, a music manuscript, metal armour and an architect's T-square. This pile of items resembles, deliberately, the geometric and architectural gear strewn across the floor in Albrecht Dürer's print Melancholy – except in this case, the gloomy mess is caused by this grinning deity and the turmoil he can unleash.

"Love looks not with the eyes, but with the mind, / And therefore is winged Love painted sightless," penned the Bard, just before this work was created around the early 1600s. But the painter's god is not unseeing. He gazes directly at the observer. That face – sardonic and ruddy-cheeked, staring with bold assurance as he poses naked – is the same one that shrieks in fear in The Sacrifice of Isaac.

When the Italian master painted his multiple portrayals of the identical unusual-appearing youth in Rome at the start of the seventeenth century, he was the most celebrated religious painter in a city enflamed by Catholic revival. Abraham's Offering reveals why he was sought to adorn sanctuaries: he could take a scriptural narrative that had been portrayed numerous occasions before and render it so new, so unfiltered and visceral that the terror seemed to be happening immediately before the spectator.

Yet there was another aspect to the artist, apparent as quickly as he came in Rome in the winter that concluded the sixteenth century, as a artist in his early 20s with no mentor or patron in the urban center, just talent and audacity. Most of the works with which he captured the sacred metropolis's attention were everything but devout. What may be the absolute first hangs in the UK's art museum. A youth parts his crimson lips in a scream of agony: while stretching out his dirty digits for a fruit, he has rather been bitten. Boy Bitten By a Lizard is eroticism amid squalor: viewers can see the painter's dismal chamber reflected in the cloudy waters of the glass vase.

The boy sports a pink flower in his coiffure – a emblem of the sex trade in early modern painting. Venetian artists such as Titian and Jacopo Palma depicted courtesans grasping blooms and, in a painting destroyed in the second world war but documented through images, the master represented a renowned female prostitute, holding a bouquet to her bosom. The message of all these floral signifiers is clear: intimacy for purchase.

What are we to interpret of Caravaggio's erotic portrayals of boys – and of one adolescent in specific? It is a inquiry that has split his commentators ever since he gained widespread recognition in the twentieth century. The complicated historical reality is that the artist was neither the queer icon that, for example, Derek Jarman put on film in his 1986 movie Caravaggio, nor so completely devout that, as certain art historians improbably assert, his Youth Holding Fruit is in fact a likeness of Christ.

His initial works indeed make overt sexual suggestions, or including offers. It's as if the painter, then a destitute young artist, aligned with the city's sex workers, offering himself to survive. In the Uffizi, with this thought in consideration, viewers might turn to an additional early creation, the sixteenth-century masterwork the god of wine, in which the deity of alcohol gazes coolly at the spectator as he begins to untie the dark sash of his garment.

A several years after the wine deity, what could have driven Caravaggio to create Amor Vincit Omnia for the artistic patron the nobleman, when he was finally growing almost established with important ecclesiastical projects? This profane non-Christian god resurrects the sexual provocations of his early works but in a more powerful, unsettling way. Fifty years afterwards, its hidden meaning seemed clear: it was a portrait of the painter's companion. A English visitor viewed the painting in about 1649 and was told its figure has "the physique and countenance of [Caravaggio's|his] owne boy or assistant that laid with him". The name of this adolescent was Francesco.

The artist had been deceased for about forty annums when this account was recorded.
