from Greek hieroskope, observer of sacred things
Ancient ritual killings by Lusitanian and Vetton peoples for divination and war

- Hieroscopes may have functioned similarly to Celtic druids
What it is
Ancient practices in the Iberian Peninsula involved killing prisoners of war to gain divine insight. Classical authors attribute these acts to the Lusitanians and other northern Celtic groups. A specialist called a hieroscope performed the rituals. The goal was to extract prophecies from the victim's body. This form of sacrifice served divinatory purposes rather than simple offering.
Where it comes from
The custom appears in works by Strabo, Plutarch, and Diodorus. These writers describe it as a tradition of the Lusitanians and mountain-dwelling peoples. Archaeological finds at Bletisama support the existence of such rites. Historians debate whether these accounts reflect reality or Roman bias. Some suggest the practice was exceptional, while others see it as frequent.
How it is done
A prisoner was covered with coarse cloaks before the ritual. The hieroscope struck the victim beneath the vitals. Omens were read from how the person fell. Blood flow and convulsions were also observed. In some cases, the right hand was cut off and offered to gods. Animal sacrifices sometimes accompanied these human acts.
Tools and materials
Coarse cloaks covered the victim during the ceremony. The right hand of the captive served as an offering to deities. The body itself provided tokens for touch and vision. Animals like goats and horses were also sacrificed alongside humans.

What it is for
These rituals aimed to foresee future events, especially before war. They sealed pacts between groups. The Lusitanians dedicated these acts to warrior deities like Neto and Cosus. The practice sought protection and success in battle through divine signs.
Who does it
Strabo names the hieroscope as the key figure. Scholars link this role to a priestly class similar to Gaulish druids. These specialists may have managed temples and calendars. Their status ranged from occasional chieftains to dedicated religious castes.
Peoples and places
The Lusitanians practiced these rites extensively. The Vettones are also described by Plutarch as performing similar sacrifices. Other northern peninsular mountain peoples participated. Similar customs appear among Scythians and Cimbri tribes across Eurasia.

Belief worlds
What people believe
The people worshipped native warrior gods identified with Ares. Deities included Neto, Cosus, and Tarbucellus. Sacrifices honored these figures for power and victory. The belief system connected physical death to spiritual foresight and divine favor.
When it is done
Rituals occurred before marching to war. They marked the sealing of important pacts. Funeral ceremonies for leaders like Viriathus likely included sacrifices. The practice persisted until Roman authorities intervened in the first century BC.
How scholars and sceptics see it
Modern historians analyze classical texts with caution due to potential ethnocentrism. Spanish and Portuguese archaeology provides corroborating evidence. Researchers note similarities between Iberian hieroscopes and Celtic druids. Some argue the absence of druids in Hispania explains the lack of a formal caste.
Cautions and what is closed
Roman law outlawed human sacrifice in 97 BC under Publius Licinius Crassus. Despite this, the Vetton Bletonesii tribe continued the practice until 94 BC. Roman authorities eventually suppressed these rites in Gaul and Africa. The topic remains controversial due to source reliability.
Compare and confuse
Similar practices exist among Gaulish druids who read blood flow. Scythians sacrificed prisoners to Ares and removed arms. The Cimbri priestesses examined entrails of drained prisoners. These parallels suggest shared Indo-European ritual traditions.
