(1605), where Pope Adrian IV compares a well-run government to a body in which "all parts performed their functions, only the stomach lay idle and consumed all"; the fable is also alluded to in John of Salisbury's Policraticus (Camden's source) and William Averell's A Marvailous Combat of Contrarieties (1588). Other sources have been suggested, but are less certain. Shakespeare might also have drawn on Livy's Ab Urbe condita, as translated by Philemon Holland, and possibly a digest of Livy by Lucius Annaeus Florus; both of these were commonly used texts in Elizabethan schools. Machiavelli's Discourses on Livy were available in manuscript translations, and could also have been used by Shakespeare. He might also have made use of Plutarch's original source, the Roman Antiquities of Dionysius of Halicarnassus, as well as on his own knowledge of Roman custom and law. Date and text Most scholars date Coriolanus to the period 1605–10, with 1608–09 being considered the most likely, although the available evidence does not permit great certainty. The earliest date for the play rests on the fact that Menenius's fable of the belly is derived from William Camden's Remaines, published in 1605. The later date derives from the fact that several other texts from 1610 or thereabouts seem to allude to Coriolanus, including Ben Jonson's Epicoene, Robert Armin's Phantasma and John Fletcher's The Woman's Prize, or the Tamer Tamed. Some scholars note evidence that may narrow down the dating to the period 1607–09. One line may be inspired by George Chapman's translation of the Iliad (late 1608). References to "the coal of fire upon the ice" (I.i) and to squabbles over ownership of channels of water (III.i) could be inspired by Thomas Dekker's description of the freezing of the Thames in 1607–08 and Hugh Myddleton's project to bring water to London by channels in 1608–09 respectively. Another possible connection with 1608 is that the surviving text of the play is divided into acts; this suggests that it could have been written for the indoor Blackfriars Theatre, at which Shakespeare's company began to perform in 1608, although the act-breaks could instead have been introduced later. The play's themes of popular discontent with government have been connected by scholars with the Midland Revolt, a series of peasant riots in 1607 that would have affected Shakespeare as an owner of land in Stratford-upon-Avon; and the debates over the charter for the City of London,
