Alexander the Great UFO Flying Shields: The Jaxartes River Incident (329 BC)

By /

The Alexander the Great UFO flying shields claim says his army saw silver discs at Jaxartes River in 329 BC. It traces to a 1959 book with no ancient source

Connect Paranormal examines the UFO theories surrounding Alexander the Great, including the alleged 329 BC Jaxartes River incident and the siege of Tyre claim.

TL;DR: The claim that Alexander the Great saw “gleaming silver shields” diving at his army in 329 BC at the Jaxartes River appears in modern UFO literature but in no surviving ancient text. Historian Spencer McDaniel and Greek historian Yannis Deliyannis both traced the story to Frank Edwards‘s 1959 book “Stranger than Science,” in which Edwards made the claim without citing any source. All five main surviving ancient accounts of Alexander (Arrian, Plutarch, Diodorus Siculus, Quintus Curtius Rufus, and Justin) describe the Jaxartes campaign without mentioning aerial phenomena. The ancient sources do mention silver-plated shields in Alexander’s army, but as decorated military equipment, not aerial objects. Sources linked below.

Timeline

329 BC: Alexander the Great’s army reaches the Jaxartes River (modern Syr Darya) in Central Asia. He founds Alexandria Eschatê (“Alexandria the Farthest,” modern Khujand, Tajikistan) and crosses the river to defeat a Scythian force. Ancient sources (Arrian, Curtius Rufus) describe the crossing and battles in detail. No aerial phenomena are mentioned.

c. 327 BC: According to Quintus Curtius Rufus (Histories of Alexander 8.5.4), after his victories in Central Asia, Alexander decorated his soldiers’ shields with silver plates and horses’ bridles with gold, to mark their status. These silver shields give Alexander’s elite hypaspist unit the name “Argyraspides” (Silver Shields) in later sources. This is the only “silver shields” reference in the ancient record connected to Alexander.

1st century CE: Quintus Curtius Rufus writes the Historiae Alexandri Magni, likely during the reign of Claudius or Vespasian. His account is one of the five main ancient sources. He records the Jaxartes crossing, the founding of Alexandria Eschatê, and the silver-plating of shields, but no aerial incident.

2nd century CE: Arrian writes the Anabasis of Alexander, considered the most reliable account. His record of the Jaxartes campaign mentions the river crossing, Scythian skirmishes, and the foundation of Alexandria Eschatê. No aerial phenomena.

1959: Frank Edwards publishes “Stranger than Science” (Lyle Stuart, New York). In it, he claims Alexander “tells of two strange craft that dived repeatedly at his army until the war elephants, the men, and the horses all panicked and refused to cross the river.” Edwards describes the objects as “great shining silvery shields, spitting fire around the rims.” He cites no ancient source.

2009: Greek historian Yannis Deliyannis publishes a post on his blog Chronicon Mirabilium tracing the Alexander UFO story to Edwards and finding no ancient sources. An academic paper, “Did Alexander the Great really see UFOs?”, is published on the same subject.

2018: Giorgio A. Tsoukalos, a producer on Ancient Aliens, repeats the claim on Buzzfeed Unsolved, stating: “Alexander the Great… [is said to have seen] giant flying shields. Giant shields that are glowing in the sky.” The episode receives over 9 million views.

2021: Historian Spencer McDaniel publishes “No, Alexander the Great Didn’t See Flying Saucers” on Tales of Times Forgotten, providing a thorough analysis of both the Edwards origin and the complete absence of the story from ancient sources.

The Alexander the Great UFO Flying Shields Claim in Modern UFO Literature

The Alexander flying shields story is one of the most widely repeated ancient UFO claims. UFOEvidence.org presents it as: “329 BC: Alexander the Great records two great ‘flying shields’… They were described as great silver shields, spitting fire around the rims.” ThinkAboutItDocs repeats the account, as do dozens of other UFO-focused websites and publications.

The story typically includes several consistent elements: two objects described as silver shields or discs, a river crossing (usually identified as the Jaxartes), panic among animals and soldiers, and the objects eventually departing skyward. These details remain remarkably stable across modern retellings, which UFO researchers sometimes cite as evidence of a genuine underlying account. However, this consistency is better explained by the retellings all copying each other (and ultimately Frank Edwards) rather than independent preservation of ancient testimony.

Connect Paranormal notes a second, related Alexander UFO claim: that during the siege of Tyre in 332 BC, “flying shields” in triangular formation assisted Alexander’s troops in breaching the city walls. This second claim circulates separately and has its own contested origin in ancient sources, specifically a passage from Curtius Rufus that some UFO researchers interpret as describing aerial objects. The Tyre account has more ambiguous ancient grounding than the Jaxartes story, though most historians read the relevant passage as describing conventional events.

The Source of the Modern Story: Frank Edwards, 1959

Historian Yannis Deliyannis’s 2009 investigation traced the Alexander Jaxartes story to its point of origin: a 1959 book by Frank Edwards, an American radio broadcaster and writer known for popular books on unusual and paranormal topics. The book, “Stranger than Science,” was published by Lyle Stuart, a New York publisher associated with controversial and unconventional titles.

Edwards wrote:

“Alexander the Great was not the first to see them nor was he the first to find them troublesome. He tells of two strange craft that dived repeatedly at his army until the war elephants, the men, and the horses all panicked and refused to cross the river where the incident occurred. What did the things look like? His historian describes them as great shining silvery shields, spitting fire around the rims… things that came from the skies and returned to the skies.”

Spencer McDaniel, writing in 2021, notes the critical problems with this passage. Edwards writes “He tells of” and “His historian describes them as,” attributing the account to Alexander and his historian. But Edwards cites no ancient source, no historian’s name, no book title, no chapter reference. As McDaniel writes: “Edwards does not cite any sources for any of these claims and it is unlikely that he ever had any.”

McDaniel concludes: “His assertion that Alexander’s army supposedly saw ‘great shining silvery shields’ in the sky does not even remotely resemble any statement in any surviving ancient source about Alexander. This claim is probably completely made up.”

What the Ancient Sources Actually Say

The five main surviving ancient accounts of Alexander’s campaigns are Arrian’s Anabasis of Alexander, Plutarch’s Life of Alexander, Diodorus Siculus’s Bibliotheca historica Book 17, Quintus Curtius Rufus’s Historiae Alexandri Magni, and Justin’s epitome of Pompeius Trogus. All five cover the Central Asian campaigns. None mention aerial phenomena at the Jaxartes crossing.

Arrian, whose account is based on the memoirs of Ptolemy I Soter (one of Alexander’s generals) and Aristobulus of Cassandreia’s history, describes the Jaxartes campaign in detail in Book 4 of the Anabasis. He records the founding of Alexandria Eschatê, the crossing of the river, the defeat of a Scythian force, and Alexander’s illness during the campaign. No aerial phenomena.

Curtius Rufus, whose account is known for including dramatic and sometimes sensational material, describes the same campaign in Books 7 and 8. He records the Jaxartes crossing and the silver-plating of shields, but in a completely different context. As McDaniel translates from Curtius 8.5.4:

“…so that he [Alexander] would never be outdone, when he stood out in other things, he attached silver plates to his shields and gold bridles to his horses, and he adorned some armors with gold and some other armors with silver.”

This is the ancient “silver shields” reference that the UFO story almost certainly distorted. Alexander’s elite hypaspist infantry later became known as the Argyraspides (“Silver Shields”) based on this distinction. These were decorated military shields carried by soldiers marching on the ground, not aerial objects.

Ancient historians routinely recorded unusual phenomena as omens and portents, including comets, eclipses, strange cloud formations, and unusual animal behavior. Arrian records a lunar eclipse before the Battle of Gaugamela and describes Alexander consulting seers about omens. If “gleaming silver shields” had appeared in the sky, causing elephants and horses to panic, every ancient source would have treated it as a major omen warranting extensive commentary. None do.

The Tyre Incident: A Separate and More Ambiguous Claim

A second Alexander UFO claim involves the siege of Tyre in 332 BC, two years before the Jaxartes campaign. This claim has somewhat more complex origins. Some UFO researchers cite a passage from Curtius Rufus describing unusual events during the siege and interpret it as describing aerial objects assisting Alexander’s assault on the walls.

The academic paper “Did Alexander the Great really see UFOs?” (2009) focuses primarily on this Tyre claim. The paper examines conflicting interpretations of the relevant Curtius passage, noting that UFO researchers cite it as evidence of aerial assistance while historians read it as describing a conventional military event or a natural phenomenon interpreted as an omen.

The paper critiques modern ufological literature’s handling of ancient sources: selectively presenting evidence, misreading metaphorical language as literal technical description, and ignoring the cultural context in which ancient historians recorded unusual events. Unlike the Jaxartes story, the Tyre claim does involve actual ancient text, but the interpretation of that text as describing UFOs requires significant departure from standard classical scholarship.

Opposing Perspective: Ancient Aerial Phenomena Research

UFO researchers who work with ancient sources argue that the absence of the Jaxartes story from surviving texts does not conclusively prove it never occurred. Alexander’s campaign generated an enormous literary output, much of which has not survived. The original campaign histories written by Callisthenes (Alexander’s official historian, executed in 327 BC), Onesicritus, Nearchus, and others are lost. Only fragments survive, quoted or paraphrased in later works.

Jacques Vallee and Chris Aubeck’s catalogue “Wonders in the Sky” (2010) applies rigorous source standards to ancient aerial accounts, including explicitly excluding cases they determined to be modern fabrications or poorly sourced. Their exclusion of the Jaxartes account represents a meaningful scholarly judgment even within the field of anomalous phenomena research.

The pattern of the story, which includes animals panicking at an aerial object, does parallel accounts from other cultures in other eras that have stronger source documentation. Researchers like those at UFOEvidence.org maintain that the consistency of such accounts across unrelated cultures warrants investigation regardless of individual case sourcing.

The evidence for and against this specific claim can be weighed by the reader. The story’s origin in a 1959 paperback without source citation, alongside the silence of all five surviving ancient accounts, are documented facts. The Nuremberg sky battle of 1561, by contrast, has genuine contemporary documentation (a broadsheet with woodcut illustration published in the same year), offering a useful comparison for evaluating source quality in historical aerial accounts.

Why This Matters: Source Criticism and the UFO Record

The Alexander the Great UFO flying shields story illustrates a broader challenge in ancient UFO research: the difficulty of distinguishing genuine ancient accounts from modern narratives attributed to ancient figures. Frank Edwards’s 1959 attribution is difficult to detect without access to the primary sources, and once the story entered UFO literature, it was repeated without verification through decades of publications, websites, and television programs.

The analysis by Deliyannis (2009) and the analysis by McDaniel (2021) both note that this pattern of uncritical repetition undermines the credibility of ancient UFO research more broadly. Cases with genuine ancient documentation, such as the Roman aerial prodigy literature recorded by Livy and Julius Obsequens, deserve careful attention. Cases traceable to modern invention do not, and conflating them weakens the overall evidentiary record.

The Metabunk community, which applies rigorous skeptical analysis to anomalous claims including UFO reports, notes that the Alexander story represents a pattern common in UFO literature: a specific, vivid description attributed to a famous historical figure, with no primary source citation, that gains credibility through repetition alone.
