The primary archaeological context of horse sacrifice are burials, notably chariot burials, but graves with horse remains reach from the Eneolithic well into historical times. Herodotus describes the execution of horses at the burial of a Scythian king, and Iron Agekurgan graves known to contain horses number in the hundreds. The Scythians had some reverence for the stag, which is one of the most common motifs in their artwork, especially at funeral sites.
Pantheon
According to Herodotus, the Scythians worshipped a pantheon of seven gods and goddesses, which he equates with Greek divinities of Classical Antiquity following the interpretatio graeca. He mentions eight deities in particular, the eighth being worshipped by the Royal Scythians, and gives the Scythian names for seven of them as follows:
Tabiti – Hestia Tabiti was presented as "Queen of the gods" around 450 BCE by King Idanthyrsos, a political guardian, she was considered the goddess of the home, ensuring prosperity to a well-functioning household.
The mode of Scythian animal sacrifice was, in the opinion of Herodotus, relatively simple. Sacrificial animals included various kinds of livestock, though the most prestigious offering was considered to be the horse. The pig, on the other hand, was never offered in sacrifice, and apparently the Scythians were loath to keep swine within their lands. Herodotus describes the Scythian manner of sacrifice as follows:
Worship of "Scythian Ares"
Although Tabiti was apparently the most important deity in the Scythian pantheon, the worship accorded to the deity Herodotus refers to as "Ares" was unique. He notes that "it is not their custom to make images, altars or temples to any except Ares, but to him it is their custom to make them". He describes the construction of the altar and the subsequent sacrifice as follows: According to Tadeusz Sulimirski, this form of worship continued among the descendants of the Scythians, the Alans, through to the 4th century CE; this tradition may be reflected in Jordanes' assertion that Attila was able to assert his authority over the Scythians through his possession of a particular blade, referred to as the "Sword of Mars".
Enarei
The Enarei were a privileged caste of hereditary priests which played an important political role in Scythian society as they were believed to have received the gift of prophesy directly from the goddess Argimpasa. The method employed by the Enarei differed from that practised by traditional Scythian diviners: whereas the latter used a bundle of willow rods, the Enarei used strips cut from the bark of the linden tree to tell the future. The Enarei were also noted for dressing themselves in the clothes of women, a custom which Herodotus understands as being reflected in the title ena-rei, glossing this as ἀνδρό-γυνοι or "man-women".
