XANTHIPPI
Antius’ wealthy, elderly wife in Salusbury’s Love or Money, whom Pamphilus describes as ‘longnosed’. She upbraids her husband for being inattentive and accuses both him and Medico of plotting against her life. She tells Antius that her money made him a man and that he must never be ungrateful to her. She says that, before they met, she was not froward but had a heart as merry as any fifty-five-year-old. When Antius calls forth a dance, she objects because the music is not solemn, but Orlando forces her to dance with him and drink (believing Antius that she is a carefree old soul who loves drink and dancing). She later chastises Antius for making ‘an honest woman’ drunk, but continues drinking all the same, all the while saying that his ruse shall not work, for she will not die to please him. She passes out from the drink, and Antius must drag her away.

XANTIPPE
An indulgent mother in the anonymous Nice Wanton. She refuses to discipline her children Ismael and Dalilah on the grounds that they are already too strictly punished at school. When she learns that both children have died because of their sinful ways, she is stricken with grief and attempts to kill herself. Prevented from suicide by Barnabas, she accepts his spiritual guidance.
