Duncan—Macol

Duncan—Macol is a relationship of adoption and care concealed beneath an assumed biological parentage. Its late revelation complicates Macol’s return as Duncan’s avenger: Duncan is not his natural father, but he is the man who raised him, while Banco is both Macol’s biological father and another person whose death he intends to avenge. The distinction makes filial obligation in the play more than a matter of blood, and places Macol’s political claim to a future dynasty beside his debts to two fathers.

Adoption and the Public Story

For much of the court’s life, Macol was taken to be the son of Duncan and Lady Duncan. That public understanding had been deliberately maintained: Lady Duncan says that she secretly left the court before Macol was born so that no one would know she was not pregnant. Everyone consequently regarded Macol as the child of Duncan and Lady Duncan, although the account Lady Duncan gives at the confrontation overturns both parts of that assumption. Duncan had adopted Macol, and Banco—not Duncan—was his father by birth.

The concealment served Duncan’s expressed desire for an heir. Lady Duncan explains that Duncan wanted one, and the court’s belief that Macol was his son supplied the appearance of a direct family succession. The play thus distinguishes the fact of adoption from the public fiction surrounding it: Duncan’s parenthood was not biological, but neither was it merely a title invented after the event. Lady Duncan states that he looked after Macol, giving their bond a history of care even as she exposes the false account of his birth.

Care, Education, and Filial Debt

Duncan’s care is made concrete by Lady Duncan’s account that he sent Macol to Carthage University. The detail establishes a practical connection between the two beyond the public claim that they were father and son: Duncan supported Macol’s education and future. The evidence does not describe their private life or Macol’s response to that upbringing, but the sequence of care and education gives weight to Lady Duncan’s later insistence that Macol owes Duncan obligations.

When Macol declares that he will take up Banco’s name and found a dynasty lasting for centuries, Lady Duncan counters that Duncan looked after him and that he must carry on the family name. Her appeal places inheritance in the language of duty and remembrance rather than simply natural descent. Macol refuses to surrender his own name, yet says he will avenge both his natural and adoptive fathers. He therefore acknowledges the relationship with Duncan even while asserting a separate dynastic future. The tension is not resolved by choosing one father over the other: Macol claims a filial debt to both, but does not accept Lady Duncan’s prescription for how Duncan’s family name should continue.

Revelation at Macol’s Return

The relationship becomes politically consequential when Lady Duncan identifies Macol as Duncan’s son by adoption at the moment he has returned from Carthage with a large, powerful army. She tells Macbett that the country is against him and that Macbett has run out of friends; the crowd’s shouts for Macol make the returning heir a public alternative to the ruler. Lady Duncan then urges Macol to kill Macbett. The family revelation is therefore delivered amid a struggle over power, not in a private recollection separated from political events.

Macol’s declared intention to avenge his fathers joins personal grievance to his challenge against Macbett. His appeal to Banco’s natural paternity also revises the apparent family line on which Duncan’s rule had rested: the man presented to the court as Duncan’s son descends by blood from Banco, while Duncan’s relationship to him rests on adoption and care. Yet Macol does not simply replace one lineage with another. He intends to retain his name and establish a dynasty of his own, even as Lady Duncan urges continuity with Duncan’s family. The exposed relationship supplies competing grounds for succession—public parentage, adoptive duty, and biological descent—without making them agree.

The Relationship’s Unsettled Legacy

Lady Duncan’s final appeal stresses Macol’s obligations to Duncan’s memory and calls him ungrateful. Macol’s stated plan to avenge both fathers partly answers that charge, but his insistence on his own name resists the form of remembrance she demands. Duncan’s place in Macol’s life is consequently neither erased by the revelation about Banco nor allowed to determine Macol’s political identity. Adoption has created a genuine debt, while blood and ambition pull the future toward another name and a new dynasty.

The relationship’s significance lies in that unresolved coexistence. Duncan wanted an heir and cared for Macol; Macol, once revealed as his adopted rather than natural son, still counts him among the fathers whose deaths require vengeance. But filial loyalty does not guarantee continuation of the adoptive father’s family name or political order. At the very point when Macol is presented as the answer to Macbett’s isolation, the story makes his legitimacy and inheritance unstable: the apparent son of Duncan is also Banco’s natural son, and he intends to found a dynasty on his own terms.
