Sirente Crater - Analysis and Interpretation

Analysis and Interpretation

An impact generating a crater the size of one at Sirente would have been visible from a great distance. Skyward it would have first been seen as a strip of fire that turned into a fireball before culminating in a pyrotechnic bolide. Although the crater lake was suggested to be just part of a larger crater field: comprising about 30 individual depressions in the Sirente area, studies have shown the "crater field" is more likely to be the result of human activity. Radiocarbon has fixed the formation of the main crater within the 4th and 5th centuries AD. In this period, the territory was part of the Roman municipium of Superaequum. A local Roman village belonging to Superaequum is known to have been suddenly abandoned possibly in consequence to fire during the 4th century. Christian catacombs dating to the same period reveal bodies were piled-up hurriedly in a manner indicating a public calamity.

A story, taken from the oral traditions of Abruzzo, concerning the region's religious conversion from Paganism to Christianity possibly records the impact event in the 5th century AD.

"It was in the afternoon...an uproar hit the mountain and quartered the giant oaks announcing the violent arrival of the Goddess. A sudden and intense heat overwhelmed the people and a shout echoed all around, splitting the air with its trail of violence All of a sudden, over there, in the distance, in the sky, a new star, never seen before, bigger than the other ones, came nearer and nearer, appeared and disappeared behind the top of the eastern mountains. Peoples’ eyes looked at the strange light growing bigger and bigger. Soon the star shone as large as a new sun. An irresistible, dazzling light pervaded the sky. The oak leaves shuddered, discoloured, and curled up. The forest lost its sap.
"The Sirente was shaking. In a tremendous rumble the statue sank into a sudden chasm. The satyrs and the Bacchantes fell down senseless. A huge silence fell. It seemed as if time had stopped in the ancient wood near the temple at the foot of the Sirente, and it looked like the mountain had never existed. The entire valley became dumb. Not a breath of wind could be heard, nor a sheep bleating from the numerous herds, nor a rustle from the strong trees, nor a human sound. After an endless period of time, when stars shone in the sky without the moon, a new breeze came to stir the leaves; sheep were heard again and the Mountain was dressed in the light of a new dawn.
"Faint stars disappeared, blue sky slowly came back and the Sirente became a golden mountain in the first rays of the new sun. It looked like the Valley was full of roses. Newly awake, men listened closely to the death rattle of the Goddess at the foot of the wood; and then they saw the statue of the Madonna with the Holy Child in her arms who was sitting on a throne of light and was surrounded by light."

The location and contemporaneous formation of the Sirente impact has led some researchers to re-examine the historic occasion when Constantine I was said to have had a vision prompting his conversion to Christianity.

"He said that about noon, when the day was already beginning to decline, he saw with his own eyes the trophy of a cross of light in the heavens, above the sun, and bearing the inscription, Conquer by this. At this sight he himself was struck with amazement, and his whole army also, which followed him on this expedition, and witnessed the miracle". From XXIX, Life of Constantine by Eusebius.

Swedish scientist Jens Ormö noted that the Roman Emperor and his military forces were camped only 60 mi (97 km) WSW from the impact site shortly before the battle of the Milvian Bridge on 28 October 312. Though a coincidence between the two events is speculation, the hypothesis that the Sirente impact might have been mistaken for a divine act was widely reported in the media.
