Question: What was Thoas's grandfather punished for?

Context paragraphs:
Ornytion: In Greek mythology, Ornytion (Greek: Ὀρνύτιων ) or Ornytus (Ὄρνυτος) was a son of Sisyphus, brother of Glaucus, Almus and Thersander, and father of Phocus and Thoas.

Euneus: In Greek mythology, Euneus (Εὔνηος) was a son of Jason and Queen Hypsipyle of Lemnos; he had a twin brother whose name is variously given as Nebrophon, Thoas or Deipylus.  They were separated from their mother after she was exiled from the island for having spared her own father Thoas.  Later, the brothers participated in the funeral games of Opheltes (Archemorus), for whose death Hypsipyle was responsible.

Fratricide Punished: Fratricide Punished, or "The Tragedy of Fratricide Punished: or Prince Hamlet of Denmark", is the English name of a German-language play of anonymous origins and disputed age.  Due to similarities of plot and dramatis personae, it is considered to be a German variant of the English play "Hamlet", though possibly not William Shakespeare’s "Hamlet", and is a problematic figure in discussions of Hamlet Q1 and the so-called Ur-Hamlet.  Such discussions have helped to raise interest in the text, which primarily lived in obscurity before the discovery of Q1 in 1823.  "Fratricide Punished" was first published in German from a written manuscript in 1781 and translated to English by Georgina Archer in 1865.  Though the play is readily available online both in English and in German, the manuscript has been lost since its initial publication, and all subsequent editions of the text are, as such, at a remove from the original.  "Fratricide Punished" is often referred to by its German title "Der Bestrafte Brudermord," or "Tragoedia der bestrafte Bruder-mord oder: Prinz Hamlet aus Dännemark."

Aeinautae: Aeinautae (Greek: Ἀειναῦται , "Aeinautai", from "aeí" always and "naûtai" sailors) were magistrates at Miletus around 600 BC, consisting of the chief men in the state, who obtained the supreme power on the deposition of the tyrants, Thoas and Damasenor.  Whenever they wished to deliberate on important matters, they embarked on board ship (hence their name), put out at a distance from land, and did not return to shore until they had transacted their business.

Thoas (Tauri king): In Greek mythology, Thoas was a son of the god Dionysus and Ariadne, the daughter of Cretan king Minos.  Some, however, consider him to be Theseus’s son, together with his brother Oenopion.  Rhadamanthus, Ariadne's uncle, bequeathed Thoas the island of Lemnos, over which he reigned until his daughter Hypsipyle, unable to kill her own father to avenge the offenses against the Lemnian women, tied him secretly in an oarless boat and sent him adrift into the Aegean Sea.  He was carried to the island of Oinoie, where he consorted with the nymph of the island, also called Oinoie, and had by her a son Sicinus, who later had the island renamed after himself.  Thoas eventually arrived at Tauris, in the Crimea, where he was made king and where Artemis installed Agamemnon's daughter Iphigeneia as her temple's priestess.

Thoas (king of Corinth): In Greek mythology, Thoas was a son of Ornytion and a grandson of Sisyphus.  According to Pausanias, Thoas remained in Corinth, succeeding his father as its ruler, while his brother Phocus led a colony to Tithorea.  Thoas was the father of Damophon, Damophon of Propodas, and Propodas of Doridas and Hyantidas.  During the reign of the latter two, Corinth was seized by the Dorians under the command of Aletes, son of Hippotes.  The brothers handed control of Corinth to him and were allowed to remain in the city, while the rest of the people were expelled.

Papilio thoas: Papilio thoas, the king swallowtail or Thoas swallowtail, is a butterfly of the family Papilionidae.  It is found in the southernmost United States, Mexico, Central America and South America (as far south as Argentina and Uruguay).  The species is easily confused with the giant swallowtail, which it closely resembles in both larval and adult stages.  The caterpillars feed on the leaves of citrus plants (Rutaceae).  They have also been reported as feeding on a member of the genus "Piper".

Bobo doll experiment: The Bobo doll experiment was the collective name of experiments conducted by Albert Bandura in 1961 and 1963 when he studied children's behavior after watching an adult model act aggressively towards a Bobo doll, a toy that gets up by itself to a standing position when it is knocked down.  There are different variations of the experiment.  The most notable experiment measured the children's behavior after seeing the model get rewarded, get punished, or experience no consequence for beating up the bobo doll.  The experiments are empirical approaches to test Bandura's social learning theory.  The social learning theory claims that people learn through observing, imitating, and modeling.  It shows that people not only learn by being rewarded or punished (behaviorism), but they can also learn from watching somebody else being rewarded or punished (observational learning).  These experiments are important because they sparked many more studies on the effects of observational learning.  The studies not only give us new data, but this data has practical implications, e.g. how children can be influenced from watching violent media.

Sisyphus: In Greek mythology Sisyphus or Sisyphos ( ; Greek: Σίσυφος , "Sísuphos ") was the king of Ephyra (now known as Corinth).  He was punished for his self-aggrandizing craftiness and deceitfulness by being forced to roll an immense boulder up a hill, only to watch it come back to hit him, repeating this action for eternity.  Through the classical influence on modern culture, tasks that are both laborious and futile are therefore described as Sisyphean ( ).

Day-fine: A day-fine, day fine, unit fine or structured fine is a unit of fine payment that, above a minimum fine, is based on the offender's daily personal income.  A crime is punished with incarceration for a determined number of days, or with fines.  As incarceration is a financial punishment, in the effect of preventing work, a day-fine represents one day incarcerated and without salary.  It is argued to be just, because if both high-income and low-income population are punished with the same jail time, they should also be punished with a proportionally similar income loss.  An analogy may be drawn with income tax, which is also proportional to the income, even progressively.
