Đại Việt sử ký tiền biên: Ngô Thì Sĩ and the poisoning hypothesis

The series' fourth reading of Lê Long Đĩnh's death does not come from the main chronicle. It comes from a later history, written in the eighteenth century, printed after its author was dead, and quoted on the site for one reason: it is the source of the poisoning hypothesis. This page is about that book.

What the Tiền biên is

The Đại Việt sử ký tiền biên — the “earlier compilation” of Đại Việt's annals — was written by Ngô Thì Sĩ, an eighteenth-century historian who lived from 1726 to 1780. It runs to seventeen quyển: seven of Ngoại kỷ, covering the legendary and early periods, and ten of Bản kỷ, from the legendary kings to the end of Ming rule in the fifteenth century. The work was revised by his son, Ngô Thì Nhậm.

Ngô Thì Sĩ did not see it printed. The first printing came in 1800, in the Cảnh Thịnh era of the Tây Sơn dynasty, twenty years after his death. That posthumous printing is the reason the site says the Tiền biên was “printed in 1800” rather than published by its author.

How it survives

The survival history is more fragile than the Toàn thư's. The original 1800 print is reported lost; the surviving copies are early Nguyễn reprints made from the Tây Sơn blocks, in which some characters were removed. A modern Vietnamese translation was published by the Social Sciences Publishing House in Hanoi in 1997, and a 2018 Hồng Đức edition exists in 773 pages (ISBN 9786048948245). The National Library of Vietnam holds the catalogue record for that edition.

There is no verified open full text online that this site can point to. A catalogue record is not a readable text, and the Wikipedia page's e-book link is dead. The honest position for a source page is therefore: the book survives in print and in translation, but not in a form that can be linked and read freely.

What the series takes from it

The series quotes the Tiền biên for two related passages, and labels them carefully. Ngô Thì Sĩ calls the epithet “Ngọa Triều” vulgar and baseless — a judgement, not a chronicle entry — and he records an old question, introduced as something “someone asked”: perhaps the Lý family had the king poisoned while he was ill and concealed it, so the histories do not say. The site does not present this as fact. It calls it an inference written nearly eight centuries later, with no contemporary evidence, belonging to the Tiền biên and not to the Toàn thư.

The distinction between the two books is the point of the reading. The Toàn thư records the death, the epithet and the wild-history note. The Tiền biên adds a later interpretation of them. Keeping the two apart is what allows the series to stage four readings without collapsing them into one.

What this page does not claim

It does not claim that Ngô Thì Sĩ proved a poisoning. His passage is a hypothesis framed as a question, and it names the Lý family, not Lý Công Uẩn. It does not claim that the 1800 printing survives in its original form, because the original print is reported lost. It does not quote the full passage, because the wording available to this site is second-hand, from a modern translation quoted by a secondary source; the paraphrase is what the series uses and what this page repeats.

It also does not claim that the Tiền biên is contemporary with the events. It was written seven hundred years after 1009, and that distance is exactly why the site labels its poisoning story a hypothesis.

Why a later book still matters

Because the series is about how the record is read, not only about what it says. A later historian's doubt is part of the story: it shows that the silence around Lê Long Đĩnh's death was already being filled long before the drama existed. The Tiền biên is the clearest evidence that the argument over 1009 is old, and that the question — a tyrant, or a victim of the victor's pen? — was being asked in the eighteenth century.

That is the role the book plays here: not the record, but the record's most consequential reader. The series stages the reading; the source page says where it came from.
