the curse that Mercutio swore. The families are reconciled by their children's deaths and agree to end their violent feud. The play ends with the Prince's elegy for the lovers: "For never was a story of more woe / Than this of Juliet and her Romeo." Sources Romeo and Juliet borrows from a tradition of tragic love stories dating back to antiquity. One of these is Pyramus and Thisbe, from Ovid's Metamorphoses, which contains parallels to Shakespeare's story: the lovers' parents despise each other, and Pyramus falsely believes his lover Thisbe is dead. The Ephesiaca of Xenophon of Ephesus, written in the 3rd century, also contains several similarities to the play, including the separation of the lovers, and a potion that induces a deathlike sleep. One of the earliest references to the names Montague and Capulet is from Dante's Divine Comedy, who mentions the Montecchi (Montagues) and the Cappelletti (Capulets) in canto six of Purgatorio: However, the reference is part of a polemic against the moral decay of Florence, Lombardy, and the Italian Peninsula as a whole; Dante, through his characters, chastises German King Albert I for neglecting his responsibilities towards Italy ("you who are negligent"), and successive popes for their encroachment from purely spiritual affairs, thus leading to a climate of incessant bickering and warfare between rival political parties in Lombardy. History records the name of the family Montague as being lent to such a political party in Verona, but that of the Capulets as from a Cremonese family, both of whom play out their conflict in Lombardy as a whole rather than within the confines of Verona. Allied to rival political factions, the parties are grieving ("One lot already grieving") because their endless warfare has led to the destruction of both parties, rather than a grief from the loss of their ill-fated offspring as the play sets forth, which appears to be a solely poetic creation within this context. The earliest known version of the Romeo and Juliet tale akin to Shakespeare's play is the story of Mariotto and Ganozza by Masuccio Salernitano, in the 33rd novel of his Il Novellino published in 1476. Salernitano sets the story in Siena and insists its events took place in his own lifetime. His version of the story includes the secret marriage, the colluding friar, the fray where a prominent citizen is killed, Mariotto's exile, Ganozza's forced marriage, the potion plot,
