Robert Greene (1558–1592) was an English author, playwright, and poet, known for his prodigious output and colourful life during the late 16th century, part of the vibrant Elizabethan era of literature. He is remembered not only for his literary contributions but also for his purported tumultuous lifestyle, which reportedly involved various forms of excess. Greene earned a BA from St. John's College, Cambridge in 1580, followed by an MA in 1583 from Clare College. Greene's works demonstrate a profound knowledge of classical literature, indicative of an accomplished education. His writing is characterized by its wit, often directed at his contemporaries and imbuing his text with a satirical edge. 'Alphonsus, King of Aragon' is one such work that exemplifies Greene's literary style, combining romantic plots with classical references. Despite its specific narrative, the play is recognized generally for its exploration of human themes such as ambition, power, and deceit, reflecting Greene's broader interest in the moral psychology of his characters. Greene's charm and influence on Elizabethan literature are undeniable, although his life and work were often shadowed by controversy, not least when he cautioned against an 'upstart crow', which many have interpreted as a reference to William Shakespeare. Greene's contributions to literature remain a testament to the rich tapestry of Elizabethan playwriting and storytelling.
