Main articles: Ilium (novel) and Olympos (novel)
The series centers on three main character groups: that of the scholic Hockenberry, Helen and Greek and Trojan warriors from the Iliad; Daeman, Harman, Ada and the other humans of Earth; and the moravecs, specifically Mahnmut the Europan and Orphu of Io. The novels are written in first-person, present-tense when centered on Hockenberry's character, but features third-person, past-tense narrative in all other instances. Much like Simmons' Hyperion where the characters' stories are told over the course of the novels and the actual events serve as a frame, the three groups of characters' stories are told over the course of the novels and their stories do not begin to converge until the end.
The "old-style" humans of Earth exist at what the post-humans claimed would be a stable, minimum herd population of one million. In reality, their numbers are much smaller than that, around 300,000, because each woman is allowed to have only one child. Their DNA incorporates moth genetics which allows sperm-storage and the choice of father-sperm years after sexual intercourse has actually occurred. This reproductive method causes many children not to know their father, as well as helps to break incest taboos in that the firmary, which controls the fertilization, protects against a child of close relatives being born. The old style humans never appear any older than about 40 since every twenty years they are physically rejuvenated.
Named after the roboticist Hans Moravec, they are autonomous, sentient, self-evolving biomechanical organisms that dwell on the Jovian moons. They were seeded throughout the outer Solar System by humans during the Lost Age. Most moravecs are self-described humanists and study Lost Age culture, including literature, television programs and movies.
Dead scholars from previous centuries that were rebuilt by the Olympian gods from their DNA. Their duties are to observe the Trojan War and report the discrepancies that occur between it and Homer's Iliad.
As much of the action derives from fiction involving gods and wizards, Simmons rationalises most of this through his use of far-future technology and science, including:
What follows is a definition of terms that are either used within Ilium or are related to its science, technology and fictional history:
Simmons references such historical figures, fictional characters and works as Christopher Marlowe, Bram Stoker's Dracula, Plato, Gollum, the Disney character Pluto, Samuel Beckett, and William Butler Yeats' "The Second Coming", among others. As well as referencing these works and figures, he uses others more extensively, shaping his novel by the examples he chooses, such as 9/11 and its effects on the Earth and its nations.
Ilium is thematically influenced by extropianism, peopled as it is with post-humans of the far future. It therefore continues to explore the theme pioneered by H. G. Wells in The Time Machine, a work which is also referenced several times in Simmons' work. One of the most notable references is when the old woman Savi calls the current people of Earth eloi, using the word as an expression of her disgust of their self-indulgent society, lack of culture and ignorance of their past.
Ilium also includes allusions to the work of Nabokov. The most apparent of these are the inclusion of Ardis Hall and the names of Ada, Daeman and Marina, all borrowed from Ada or Ardor: A Family Chronicle. The society that the old-style humans live in also resembles that of Antiterra, a parallel of our Earth circa 19th century, which features a society in which there exists a lack of repression and Christian morality, shown by Daeman's intent to seduce his cousin. Simmons also includes references to Nabokov's fondness for butterflies, such as the butterfly genetics incorporated in the old-style humans and Daeman's enthusiasm as a lepidopterist.
Mahnmut of Europa is identified as a Shakespearean scholar as in the first chapter he is introduced where he analyzes Sonnet 116 in order to send it to his correspondent, Orphu of Io, and it is here that Shakespeare's influence on Ilium begins. Mahnmut's submersible is named The Dark Lady, an allusion to a figure in Shakespeare's sonnets. There is also, of course, The Tempest's presence in the characters of Prospero, Ariel and Caliban. There are also multiple references to other Shakespeare works and characters such as Falstaff, Henry IV, Part I and Twelfth Night. Shakespeare himself even makes an appearance in a dream to Mahnmut and quotes from Sonnet 31.
Proustian memory investigations had a heavy hand in the novel's making, which helps explain why Simmons chose Ada or Ardor: A Family Chronicle over something more well-understood of Nabokov's, such as Pale Fire. Ada or Ardor was written in such a structure as to mimic someone recalling their own memories, a subject which Proust explores in his work À la recherche du temps perdu. Orphu of Io is more interested in Proust than Mahnmut's Shakespeare, as he considers Proust "perhaps the ultimate explorer of time, memory, and perception."
Simmons' portrayal of Odysseus speaking to the old-style humans at Ardis Hall is also reminiscent of the Bible's Jesus teaching his disciples. Odysseus is even addressed as "Teacher" by one of his listeners in a way reminiscent of Jesus being addressed as "Rabbi," which is commonly translated as "Teacher".
In January 2004, it was announced that the screenplay he wrote for his novels Ilium and Olympos would be made into a film by Digital Domain and Barnet Bain Films, with Simmons acting as executive producer. Ilium is described as an "epic tale that spans 5,000 years and sweeps across the entire solar system, including themes and characters from Homer's The Iliad and Shakespeare's The Tempest."6
