This article about the development of themes in Italian Renaissance painting is an extension to the article Italian Renaissance painting, for which it provides additional pictures with commentary.
The works encompassed are from Giotto in the early 14th century to Michelangelo's "Last Judgement" of the 1530s.
The themes that preoccupied painters of the Italian Renaissance were those of both subject matter and execution- what was painted and the style in which it was painted.
The artist had far more freedom of both subject and style than did a Medieval painter.
Certain characteristic elements of Renaissance painting evolved a great deal during the period.
These include perspective, both in terms of how it was achieved and the effect to which it was applied, and realism, particularly in the depiction of humanity, either as symbolic, portrait or narrative element. 
The cover artwork features the band jumping in front of Michelangelo's 'The Last Judgment'. 
Bracci is seen in Michelangelo's poem G.193 where he laments that he never got to really know him.
He states: Scarce had I seen for the first time his eyes, Which to your living eyes were life and light, When, closed at last in death's injurious night, He opened then on God in Paradise.  
Searching for themes and considering what works and what does not work within themes enables the researcher to begin the analysis of potential codes.
In this phase, it is important to begin by examining how codes combine to form over-reaching themes in the data.
At this point, researchers have a list of themes and begin to focus on broader patterns in the data, combining coded data with proposed themes.
Researchers also begin considering how relationships are formed between codes and themes and between different levels of existing themes.
It may be helpful to use visual models to sort codes into the potential themes.
Themes differ from codes in that themes are phrases or sentences that identifies what the data "means".
They describe an outcome of coding for analytic reflection.
Themes consist of ideas and descriptions within a culture that can be used to explain causal events, statements, and morals derived from the participants' stories.
In subsequent phases, it is important to narrow down the potential themes to provide an overreaching theme.
Thematic analysis allows for categories or themes to emerge from the data like the following: repeating ideas; indigenous terms, metaphors and analogies; shifts in topic; and similarities and differences of participants' linguistic expression.
It is important at this point to address not only what is present in data, but also what is missing from the data.
conclusion of this phase should yield many candidate themes collected throughout the data process.
It is crucial to avoid discarding themes even if they are initially insignificant as they may be important themes later in the analysis process. 
According to Condivi, the poet Poliziano suggested the specific subject to Michelangelo, and recounted the story to him.
The battle depicted takes place between the Lapiths and the Centaurs at the wedding feast of Pirithous.
Pirithous, king of the Lapith, had long clashed with the neighboring Centaurs.
To mark his good intentions Pirithous invited the Centaurs to his wedding to Hippodamia, whose name ("Hippo," "Ιππο", literally translates as "horse"), and may suggest some connection to them.
Some of the Centaurs, over-imbibed at the event, and when the bride was presented to greet the guests, she so aroused the intoxicated centaur Eurytion that he leapt up and attempted to carry her away.
This led not only to an immediate clash, but to a year-long war, before the defeated Centaurs were expelled from Thessaly to the northwest.
The myth was a popular subject for Greek sculpture and painting.
The Greek sculptors of the school of Pheidias perceived the battle of the Lapiths and Centaurs as symbolic of the great conflict between order and chaos and, more specifically, between the civilized Greeks and Persian "barbarians".
Battles between Lapiths and Centaurs were depicted in the sculptured friezes on the Parthenon and on Zeus' temple at Olympia.
Scigliano suggests that Michelangelo's "Battle of the Centaurs" also reflects the themes of "Greeks over barbarians" and "civilization over savagery", but in Michelangelo's work he sees, in addition.
the triumph of "stone over flesh".
He notes that in the work itself, Michelangelo depicts his combatants using rocks against one another, and suggests that the sculptor could not have missed the coincidence that the name of the human fighters—Lapith—reflects the Latin word for stone ("lapis") and the Italian word for stone plaque ("lapide").
