Michelangelo's depiction of the Genealogy of Jesus departs from an artistic tradition for this topic that was common in medieval times, especially in stained-glass windows.
This so-called Jesse Tree shows Jesse lying prone and a tree growing from his side with the ancestors on each branch, in a visual treatment of a biblical verse.
The figures in the lunettes appear to be families, but in every case they are families that are divided.
The figures in them are physically divided by the name tablet but they are also divided by a range of human emotions that turn them outward or in on themselves and sometimes towards their partner with jealousy, suspicion, rage or simply boredom.
In them Michelangelo has portrayed the anger and unhappiness of the human condition, painting "the daily round of merely domestic life as if it were a curse".
In their constraining niches, the ancestors "sit, squat and wait".
Of the fourteen lunettes, the two that were probably painted first, the families of Eleazar and Mathan and of Jacob and Joseph are the most detailed.
They become progressively broader towards the altar end, one of the last being painted in only two days.
The Eleazar and Mathan picture contains two figures with a wealth of costume detail that is not present in any other lunette.
Prior to restoration, of all the paintings in the Sistine Chapel, the lunettes and spandrels were the dirtiest.
Added to this, there has always been a problem of poor daytime visibility of the panels nearest the windows because of "halination".
Consequently, they were the least well known of all Michelangelo's publicly accessible works.
The recent restoration has made these masterly studies of human nature and inventive depiction of the human form known once more.

Happiness, joy, love, excitement are all positive emotions and there is no arguing that these emotions contribute in large to how we act, how we think, and what we do.
In contrast there are also negative feelings such as sadness that can lead us to act in certain ways that may not necessarily be good.
Studies have been performed that have shown that positive emotions can be used to "correct" or "undo" the effects of negative emotions.
Barbara Fredrickson and Robert Levenson have come up with the undoing hypothesis.
In essence what the hypothesis states is that people might hold in the effects of their positive emotions to counterbalance the effects of their negative emotions.
Overall positive emotions help lower the potentially health-damaging cardiovascular reactivity that lingers following negative emotions.
This effect may be especially important for those most at risk for developing coronary heart disease.

There is debate among researchers as to what types of emotions works of art can elicit; whether these are defined emotions such as anger, confusion or happiness, or a general feeling of aesthetic appreciation.
The aesthetic experience seems to be determined by liking or disliking a work of art, placed along a continuum of pleasure–displeasure.
However, other diverse emotions can still be felt in response to art, which can be sorted into three categories: Knowledge Emotions, Hostile Emotions, and Self-Conscious Emotions. 
Positive emotions can undo lingering negative emotions because they put the negative emotions in a broader perspective.
If an individual can cultivate these positive emotions, he or she can use them to help cope with negative emotions.
Positive emotions help people who are distressed deal with what is occurring and move forward and away from the negative emotions.
Also, because of their broadening effect, positive emotions increase the probability of finding good in future events.
Individuals high in resiliency are those who experience more positive emotions even in the face of stress.
Having these positive emotions is what helps an individual build up resources to cope with negative emotional experiences. 
The ancestors of Jesus are listed in the Biblical books of Matthew and Luke.
This is the first known large painted series, although they were often shown in stained glass.
