Art's Job vs. Art's Mission
Every artwork has a 'job' it does (its function) and a 'mission' it was created for (its purpose). This lesson teaches you how to investigate and compare these roles for artworks from completely different worlds, which is key to a high-scoring Comparative Study.
Think of two different tools: a ceremonial golden dagger and a stainless steel kitchen knife. Both are 'knives', but their function and purpose are worlds apart. The kitchen knife's function is to cut food (utilitarian). Its purpose is to aid in cooking. The golden dagger's function might be symbolic, used in a ritual (ritualistic). Its purpose is to signify power, status, or a connection to the divine. Your Comparative Study does the same thing: it analyses artworks as 'tools' within their culture.
- 1
Select artworks with contrasting cultural origins to make comparison meaningful.
- 2
Analyse formal qualities (Criterion A) and ask: 'How do these visual choices support the work's job?'
- 3
Research the cultural context to uncover the intended purpose: Was it for a patron, a ritual, the public, or personal expression?
- 4
Compare and contrast how each artwork fulfils its function and purpose, drawing direct links between them and explaining the significance of the differences.

Criterion B: Unpacking Function and Purpose
The IB Visual Arts guide asks for an 'analysis and understanding of the function and purpose of the selected artworks... within the cultural context in which they were created'. Examiners are looking for a clear distinction between these two terms. Think of it this way:
- Function: The job the artwork performs. Is it meant to be worn, viewed in a temple, hung in a gallery, used to store something, or carried in a protest? This is about the artwork's role and interaction with its audience or environment.
- Purpose: The intention behind the artwork's creation. Why was it made? To honour a god, to sell a product, to express personal angst, to document an event, to challenge authority? This is about the artist's, patron's, or culture's motivation.
A top-band analysis demonstrates how the function and purpose are interconnected and how they are reflected in the artwork's formal qualities.
Function is the 'what it does'; Purpose is the 'why it was made'.
Analyse, don't just state. Explain how you know the function or purpose based on evidence.
Connect your analysis of function and purpose directly to your analysis of formal qualities (Criterion A).
Always consider the original cultural context, not just how we view the work today in a museum.
The Role of Cultural Context
You cannot analyse function and purpose in a vacuum. An artwork is a product of its time and place. A fertility figure from a pre-literate society has a profoundly different function and purpose from a Jeff Koons sculpture, even if both deal with themes of life and value. Your research into the cultural context is not just background information; it is the very foundation of your argument for Criterion B and C ('Analysis of cultural significance').
Research the social structure: Was it a monarchy, a democracy, a tribal society?
Investigate the dominant beliefs: What were the main religious, philosophical, or political ideologies?
Consider the art world of the time: Was the artist part of a movement? Who were the patrons? Where was art displayed?
Avoid stereotypes: Be specific. Instead of 'African art is ritualistic', say 'This specific mask from the Dogon people of Mali was used in the Dama funeral ceremony to...'.
Linking Formal Analysis to Function and Purpose
A common pitfall is to describe the formal qualities in one section (Criterion A) and then discuss function and purpose in another (Criterion B) without connecting them. A high-level analysis weaves them together. Every choice the artist made—colour, material, scale, composition—was likely in service of the work's intended function and purpose. Your job is to explain how.
Use phrases that explicitly link form to function. For example: 'The monumental scale of the statue serves its purpose of glorifying the emperor...', 'The use of ephemeral materials like unfired clay underscores the performance's function as a temporary, ritual act...', or 'The chaotic composition directly reflects the artist's purpose of conveying the disorienting experience of war.'
Synthesising Your Comparison
The final step (Criterion D) is to move beyond side-by-side descriptions and create a true synthesis. After analysing the function and purpose of each work individually, you must compare them directly. What do the similarities and differences tell us about the different cultural values, artistic traditions, or historical moments? This is where you demonstrate a holistic understanding.

Compare the function and purpose of a Nail Figure (Nkisi N'kondi) from the Kongo people (c. 19th century) and Käthe Kollwitz's print 'The Grieving Parents' (c. 1932).
- 1
In this comparative analysis, we see a fascinating divergence in the function and purpose of art as a vessel for human suffering and resolution. The Nkisi N'kondi functions as a ritual object, a physical manifestation of justice and agreement within the Kongo community. Its purpose is to house a spiritual entity that can be activated to resolve disputes or avenge wrongs, a role confirmed by the accumulation of nails and blades driven into its surface, each representing a sealed oath or matter. The jagged, aggressive texture created by these metal additions (formal qualities) directly serves its function as a powerful, intimidating arbiter. Its purpose is fundamentally communal and supernatural; it is an active agent in the legal and spiritual life of its people.
Compare the function and purpose of a page from the 'Lindisfarne Gospels' (c. 700 AD) and a 1960s psychedelic rock poster.
- 1
A comparative analysis of a carpet page from the Lindisfarne Gospels and a psychedelic rock poster by, for example, Wes Wilson, reveals a shared function of visual captivation in the service of profoundly different purposes. Both artworks function as visual portals, designed to induce a state of contemplation or altered perception through intricate, non-figurative patterns. The Gospel page, with its impossibly complex interlace and zoomorphic designs, functions as a meditative tool. Its purpose is to draw the monastic viewer into a state of spiritual focus, preparing their mind for the sacred text that follows. The painstaking detail and use of precious pigments signify the devotion and resources of the community, glorifying God through masterful craft. The function is devotional focus; the purpose is divine worship.

Function (in Visual Arts)
The practical, ceremonial, or decorative role an artwork or object plays. What does it do? Examples: utilitarian (a pot), ritualistic (a mask), commemorative (a monument), social (a mural).
