In the Unified Modeling Language, an action is a named element that is the fundamental unit of executable functionality. The execution of an action represents some transformation or processing in the modeled system. An action execution represents the run-timebehavior of executing an action within a specific behavior execution. All action executions will be executions of specific kinds of actions because Action is an abstract class. When the action executes, and what its actual inputs are, is determined by the concrete action and the behaviors in which it is used.
An action forms an abstraction of a computational procedure which is an atomicexecution and therefore completes without interruption. An action is considered to take zero time and cannot be interrupted. In contrast, an activity is a more complex collection of behavior that may run for a long duration. An activity may be interrupted by events, in which case, it does not run to completion.

Africa and De viris illustribus were partially inspired by Petrarch's visit to Rome in 1337. According to Bergin and Wilson (p. ix). It seems very likely that the inspirational vision of the Eternal City must have been the immediate spur to the design of the Africa and probably De viris illustribus as well. After returning from his grand tour, the first sections of Africa were written in the valley of Vaucluse. Petrarch recalls
The fact that he abandoned it early on is not entirely correct since it was far along when he received two invitations (from Rome and from Paris) in September 1340 each asking him to accept the crown as poet laureate. A preliminary form of the poem was completed in time for the laurel coronation April 8, 1341 (Easter Sunday).

Africa is a 1930 Walter Lantz cartoon short featuring Oswald the Lucky Rabbit.
Oswald was riding through the Egyptian desert on his camel. The camel, though looking real on the exterior, is actually mechanical because of the two ball-shaped pistons inside which Oswald manipulates with his feet like bike pedals. One day, a lion was running toward them. To defend himself, Oswald brought out a rifle but it malfunctioned. As a final resort, Oswald fired the ball pistons from the camel like a cannon and aimed into the lion's mouth. Terrified by its lumpy back, the lion runs away in panic.
Nearby where he is, Oswald saw an oasis and a palace. Upon seeing the apes dance and play instruments, the curious rabbit decides to join the fun. As he entered the palace, Oswald was greeted by the queen. The queen asked him who he is, and Oswald introduced himself in a song as well as giving advice for a possibly better lifestyle. Pleased by his visit, the queen asked Oswald if he would like to be her king. Oswald was at first uncertain, knowing he never met a queen, but immediately accepted. It turns out momentarily that the queen still has a king who shows up then throws Oswald out of the palace and into a pond full of crocodiles. Luckily, Oswald escapes unscathed and runs off into the desert.
