Title: Symposium (Xenophon)
Content:  There has been some dispute about whether Xenophon's or Plato's work was written first. Henry Graham Dakyns, a Victorian-era scholar who translated many works by both Plato and Xenophon, believed that Plato knew of this work, and that it influenced him to some degree when he wrote his own Symposium. However, most later scholars have taken one particular argument, the argument against an army of lovers in Socrates' final speech, as proof that Xenophon had based his work on Plato's, since this concept is mentioned in Plato's work. The speech seems to parody or pastiche the erotic speeches in both Plato's Symposium and Phaedrus. Though some scholars have argued that the long speech of Socrates contains later additions, and opinion is divided as to which author was first to write a Socratic symposium, recent scholarship generally holds that Xenophon wrote the Symposium in the second half of the 360s, benefiting from Plato's former Socratic literature. While Plato's Symposium consists of a series of lengthy speeches in praise of love, Xenophon's is dominated by witty repartee.

Title: Symposium (Xenophon)
Content:   The Symposium is a Socratic dialogue written by Xenophon in the late 360s B.C. In it, Socrates and a few of his companions attend a symposium (a lighthearted dinner party at which Greek aristocrats could have discussions and enjoy entertainment) hosted by Kallias for the young man Autolykos. Xenophon claims that he was present at the symposium, although this is disputed because he would have been too young to attend. The dramatic date for the Symposium is 422 B.C. Entertainment at the dinner is provided by the Syracusan and his three performers. Their feats of skill thrill the attendants and serve as points of conversation throughout the dialogue. Much of the discussion centers on what each guest is most proud of. All their answers are playful or paradoxical: Socrates, for one, prides himself on his knowledge of the art of match-making. Major themes of the work include beauty and desire, wisdom, virtue, and laughter which is evoked by Philippos the jester and the jocular discourse of the dinner guests. Xenophon demonstrates clever use of playfulness (paidia παιδία) and seriousness (spoude σπουδή) to manipulate the discussion of the above-mentioned themes in a manner appropriate to a symposium.

Title: Symposium (Plato)
Content:  The Symposium (, Sympósion ) is a philosophical text by Plato dated c. 385–370 BC. It depicts a friendly contest of extemporaneous speeches given by a group of notable men attending a banquet. The men include the philosopher Socrates, the general and political figure Alcibiades, and the comic playwright Aristophanes. The speeches are to be given in praise of Eros, the god of love and desire. In the Symposium, Eros is recognized both as erotic love and as a phenomenon capable of inspiring courage, valor, great deeds and works, and vanquishing man's natural fear of death. It is seen as transcending its earthly origins and attaining spiritual heights. This extraordinary elevation of the concept of love raises a question of whether some of the most extreme extents of meaning might be intended as humor or farce. Eros is almost always translated as "love", and the English word has its own varieties and ambiguities that provide additional challenges to the effort to understand the Eros of ancient Athens. This dialogue is one of Plato's major works, and is appreciated for both its philosophical content and its literary qualities.

Title: Symposium (Xenophon)
Content:  As part of the Socratic Corpus, the symposium was, until fairly recently, regarded as an entirely serious dialogue. Scholars thought that it was written sincerely and they largely interpreted the text literally. Bernard Huss completely changed scholars' understanding and interpretation of the work. He effectively proved that much of the dialogue is intended to be comical, satirical, and ironic. Xenophon cleverly manipulates playfulness (paidia) and seriousness (spoude) in a manner appropriate to the mood of a symposium and conducive to lighthearted discussion. Ancient authors did not comment upon the work's comedic nature, but treated it seriously as a Socratic dialogue. Modern scholars were thus predisposed to such an interpretation. Before Huss, most scholars awkwardly explained and translated certain sections of the text, but now it is understood that in such sections (for example, 2.15-2.19, 3.10, 4.18, 4.25-4.28, 4.45, 4.60-4.61, 5.1-5.2) a joke is intended.
