The Clouds is a comedy play written by the celebrated playwright Aristophanes lampooning intellectual fashions in classical Athens. It was originally produced at the City Dionysia in 423 BC and it was not well received, coming last of the three plays competing at the festival that year. It was revised between 420-417 BC and thereafter it was circulated in manuscript form. No copy of the original production survives, and scholarly analysis indicates that the revised version is an incomplete form of Old Comedy. This incompleteness, however, is not obvious in translations and modern performances. Retrospectively, The Clouds can be considered the world's first extant "comedy of ideas" and is considered by literary critics to be among the finest examples of the genre. The play also, however, remains notorious for its caricature of Socrates and is mentioned in Plato's Apology as a contributor to the philosopher's trial and execution. The play begins with Strepsiades suddenly sitting up in bed while his son, Pheidippides, remains blissfully asleep in the bed next to him. Strepsiades complains to the audience that he is too worried about household debts to get any sleep - his wife (the pampered product of an aristocratic clan) has encouraged their son's expensive interest in horses. Strepsiades, having thought up a plan to get out of debt, wakes the youth gently and pleads with him to do something for him. Pheidippides at first agrees to do as he's asked then changes his mind when he learns that his father wants to enroll him in The Thinkery, a school for wastrels and bums that no self-respecting, athletic young man dares to be associated with. Strepsiades explains that students of The Thinkery learn how to turn inferior arguments into winning arguments and this is the only way he can beat their aggrieved creditors in court. Pheidippides however will not be persuaded and Strepsiades decides to enroll himself in The Thinkery in spite of his advanced age. There he meets a student who tells him about some of the recent discoveries made by Socrates, the head of The Thinkery, including a new unit of measurement for ascertaining the distance jumped by a flea (a flea's foot, created from a minuscule imprint in wax), the exact cause of the buzzing noise made by a gnat (its rear end resembles a trumpet) and a new use for a large pair of compasses (as a kind of fishing-hook for stealing cloaks from pegs over the gymnasium wall). Impressed, Strepsiades begs to be introduced to the man behind these discoveries. The wish is soon granted: Socrates appears overhead, wafted in a basket at the end of a rope, the better to observe the Sun and other meteorological phenomena. The philosopher descends and quickly begins the induction ceremony for the new elderly student, the highlight of which is a parade of the Clouds, the patron goddesses of thinkers and other layabouts. The Clouds arrive singing majestically of the regions whence they arose and of the land they have now come to visit, loveliest in all being Greece. Introduced to them as a new devotee, Strepsiades begs them to make him the best orator in Greece by a hundred miles. They reply with the promise of a brilliant future. Socrates leads him into the dingy Thinkery for his first lesson and The Clouds step forward to address the audience.
