The painting illustrates an episode from Giovanni Boccaccio's Decameron novel Lisabetta e il testo di bassilico, reprised by John Keats's poem, Isabella, or the Pot of Basil, which describes the relationship between Isabella, the sister of wealthy medieval merchants, and Lorenzo, an employee of Isabella's brothers. It depicts the moment at which Isabella's brothers realise that there is a romance between the two young people, and plot to murder Lorenzo so they can marry Isabella to a wealthy nobleman. Isabella, wearing grey at the right, is being handed a blood orange on a plate by the doomed Lorenzo. A cut blood orange is symbolic of the neck of someone who has just been decapitated, referring to Isabella cutting off Lorenzo's head to take it with her after finding him buried. One of her brothers violently kicks a frightened dog while cracking a nut. Millais and his colleague William Holman Hunt had both produced drawings illustrating episodes from the poem, but only Millais worked his up into a full painting. Both drawings used distorted perspective and angular poses characteristic of medieval art, by which the Pre-Raphaelites were influenced. Millais also draws on the precedent of William Hogarth's satirical depictions of an arranged marriageMarriage à-la-mode.
Composition and meaning
The painting is structured with deliberately distorted perspective, elongating the right hand side of the table and flattening the figures ranged along it. Following Pre-Raphaelite theory, Millais almost eliminates chiaroscuro and exaggerates the intensity of juxtaposed colours and tones - as evidenced in the flat black tunic set against the sharply modelled white cloth of the servant at the right, whose lower body virtually disappears as his yellow stockings semi-merge with the background. Millais also carefully characterises each figure with equal precision. Another distinctive Pre-Raphaelite feature is the inclusion of images and patterns within the image as a whole. Each of the plates has a distorted picture glazed into its surface. The base of the bench on which Isabella sits contains a carving depicting a kneeling figure under which appear the letters PRB. The central motif of the thuggish brother's kicking leg and upturned chair further disturbs the equilibrium of the composition, as does the deliberately confusing "crowding" of the figures on the table and elaboration of motifs.
Hidden phallic symbols
In 2012, British art curator Carol Jacobi published an article about sexual symbols in the painting. They were all on or near the character in the front left, who is stretching out his leg and using a nutcracker. The shadow on the table near his crotch area, his leg, and the nutcracker were all argued to represent a phallus. Jacobi said: "The shadow is clearly phallic, and it also references the sex act, with the salt tipped into the shadow." She also argued that it would have been deliberate, but did not know what the painter's intention with it was. However, she stated that it was "not a Freudian slip, or a hypocritical, furtive innuendo. The imagery of masturbation and the anxieties around it and being unable to control yourself sexually would have been well known."
Adaptation
Sam Walsh painted The Dinner Party in 1980. It is one of his most complex works and is inspired by Millais' Pre-Raphaelite painting Isabella. Both paintings are in the Walker Art Gallery at Liverpool. In this interpretation, the sitters, who would never have met all at the same time, are people from all periods of its life.
