Babylonian furnaces and execution by fire

Daniel 3 repeatedly designates the furnace by the Aramaic expression ʾattûn nûrāʾ yāqidtaʾ, which can be rendered "furnace of blazing fire" or "burning fiery furnace."

The term ʾattûn designates an oven or furnace capable of reaching a high temperature.

The narrative never specifies, however, the original function of this installation.

It is therefore preferable to speak simply of a "furnace" rather than to assert that it was necessarily a brick kiln, a metallurgical furnace, or an installation specially built for executions.

The use of kilns was indispensable in ancient Mesopotamia.

The region had abundant clay, while stone and building timber were less readily available in some areas. Brick thus became one of the fundamental materials of Mesopotamian architecture.

Two main processes could be used: drying bricks in the sun and firing them.

Fired bricks were particularly useful for constructions exposed to moisture or requiring greater strength.

The great building programs of the Neo-Babylonian rulers thus required a considerable production of materials.

The existence of large-capacity kilns in the Babylonian environment therefore presents no particular historical difficulty.

Nebuchadnezzar II is particularly associated with the great construction works of Babylon.

His reign was marked by the restoration and embellishment of temples, palaces, fortifications, and monumental works.

The royal inscriptions of Nebuchadnezzar, moreover, give an important place to his activity as a builder.

In this context, the production of fired bricks and the use of large firing installations belonged to the material environment of his time.

This observation does not prove that the furnace of Daniel 3 belonged to a royal building site. It simply shows that the presence of a large installation capable of producing intense heat is perfectly compatible with the Neo-Babylonian setting of the narrative.

The hypothesis is often proposed.

A brick kiln has several characteristics that can be compared with the narrative: it must produce intense heat, allow fuel to be introduced, and have a space where the materials to be fired are placed.

Certain types of kilns also have several openings, which could help us understand how the condemned men are thrown into the fire while Nebuchadnezzar can afterward observe what is happening and approach an opening (Daniel 3.23-26).

But these comparisons are not enough to identify the furnace with certainty.

Daniel never says: "brick kiln."

The conclusion must therefore remain limited: a large kiln for industrial use is a reasonable possibility, but its exact function remains unknown.

The narrative nevertheless provides a few functional indications.

The three men are "thrown" into the furnace (Daniel 3.21-23).

Nebuchadnezzar can then look and see figures walking in the midst of the fire (Daniel 3.24-25).

Finally, he "came near to the door of the burning fiery furnace" and ordered the three men to come out (Daniel 3.26).

These indications are compatible with an installation having an opening through which the condemned were put in and another zone of access or observation.

In some ancient kilns, fuel could be introduced in a lower part while an upper or lateral opening gave access to the firing chamber.

It would nevertheless be impossible to reconstruct a precise plan of the furnace from Daniel 3 alone.

Daniel 3.22 states that the flames kill the men charged with throwing the three Judeans into the furnace. Daniel 3.26 reports, however, that Nebuchadnezzar then approaches its entrance.

There is not necessarily any contradiction between the two indications.

The soldiers have to approach the most dangerous zone closely enough to throw the condemned into the fire. Nebuchadnezzar can then stand before another opening or at a different distance.

The text specifies neither the distances, nor the configuration of the kiln, nor the time elapsed.

It would therefore be artificial to try to resolve the question by precise thermal calculations that the narrative does not allow.

The essential point remains that the heat was truly deadly for the executioners, while the three condemned men remained unharmed.

The most significant biblical comparison is found in Jeremiah 29.

The prophet sends a letter to the Judeans deported to Babylon (Jeremiah 29.1-4). In it he denounces in particular two false prophets, Ahab son of Kolaiah and Zedekiah son of Maaseiah.

Jeremiah announces:

"Nebuchadnezzar king of Babylon will put them to death before your eyes" (Jeremiah 29.21).

The next verse specifies the nature of their punishment. The exiles will use their fate in a formula of cursing that refers to men "whom the king of Babylon roasted in the fire" (Jeremiah 29.22).

This passage is particularly important because it explicitly associates three elements also present in Daniel 3:

Nebuchadnezzar;

Babylon;

an execution by fire.

Jeremiah 29.22 does not recount the episode of Daniel 3 and mentions neither Shadrach, nor Meshach, nor Abednego.

The two events must therefore not be confused.

The text nevertheless provides an independent datum within the biblical corpus: under Nebuchadnezzar, men could be condemned to a death involving fire.

This information considerably strengthens the contextual plausibility of Daniel 3.

Execution by fire no longer appears as a penalty invented solely for the needs of the furnace narrative. Jeremiah also knows of such a practice under the same sovereign and in the same Babylonian environment.

The wording of Jeremiah 29.22 must nevertheless be used with precision.

The text indicates that the two men were "roasted" or "grilled" in the fire. It does not specify that they were thrown into the same category of furnace as the one described in Daniel 3.

It would therefore be excessive to assert that Jeremiah 29 proves the existence of the exact model of furnace used against the three Judeans.

What Jeremiah confirms is more limited but nevertheless significant: putting to death by fire belongs to the context of the penalties attributed to Nebuchadnezzar.

The use of fire as a penalty is not limited to Babylon.

Genesis 38.24 reports the proposal to burn Tamar after an accusation of sexual immorality.

Leviticus 20.14 and 21.9 also mention fire in certain penalties of Israelite legislation.

Joshua 7.25 reports that the body of Achan and what belonged to him were burned after his execution.

These texts belong to different legal and historical contexts and must not be confused with Daniel 3.

They nevertheless show that the association between condemnation and fire was known in the biblical world.

Daniel 3.19 states that the king orders the furnace to be heated "seven times more" than usual.

This expression should probably not be understood as a precise scientific measurement.

To multiply a temperature exactly by seven, one would need a numerical definition of the initial temperature and an instrument for measuring the result, which obviously does not correspond to the language of the narrative.

The expression more naturally means that the furnace is to be heated with exceptional, even maximal, intensity.

The number seven may reinforce this idea of fullness or complete intensity.

But this literary dimension does not cancel the reality of the increase in the fire: Daniel 3.22 explicitly states that the heat becomes intense enough to kill the executioners.

It is sometimes tempting to attribute a precise temperature to the furnace, for example 800, 1,000, or 1,200 °C.

Such figures should be avoided in the analysis of the text.

The temperature would depend on many unknown parameters:

• nature of the fuel;
• quantity of air available;
• draft system;
• dimensions of the kiln;
• materials making up the walls;
• duration of heating;
• position of the people in relation to the hearth.

Daniel provides none of this information.

An exact temperature therefore cannot be calculated.

The only legitimate conclusion is that the narrative describes a heat intense enough to cause the rapid death of men exposed to the flames.

The death of the soldiers plays an essential role in the narrative.

Without Daniel 3.22, one could theoretically imagine that the furnace was not hot enough to kill the condemned immediately.

The text eliminates precisely this possibility.

The men who approach the fire die.

The heat therefore exerts its destructive effect normally.

When Shadrach, Meshach and Abednego remain unharmed, their survival cannot be attributed, within the logic of the narrative, to a failure of the furnace.

The miracle does not consist in the absence of fire, but in the absence of the fire's effect on those whom God protects.

The historical analysis of the furnace makes it possible to establish several elements of plausibility:

the existence of powerful kilns is compatible with Babylonian civilization;

the great building works of Nebuchadnezzar presuppose the extensive use of firing techniques;

Jeremiah 29.22 attests execution by fire under Nebuchadnezzar.

These data can illuminate the historical setting.

They do not, however, demonstrate the miracle of Daniel 3 archaeologically.

The miracle belongs to the testimony of the text: the fire, normally deadly, ceases to exercise its power over the three men.

An academic study need not confuse these two levels. It can show that the material setting of the episode is historically plausible while recognizing that the supernatural deliverance is the distinctive theological and historical claim of the biblical narrative.
