De prodigiosa specie, naturaq[ue] cometae, qui nobis effulsit altior lunae sedibus, insolita prorsus figura, ac magnitudine, anno 1577 plus septimanis 10. apodeixis tum physica tum mathematica

...the Chasm hurled sudden rays downward, straight, with varied color, very terrible (you would have said from naphtha and sulfur), toward the Northwest and the maritime regions. Then, after many struggles and concurrences made against certain order and number, the whole sky was seized by fire on every side, with globes of flames running down beyond the zenith even to the South, in which region a fragment of a rainbow, somewhat obscure, was carried along, and fire flying from its outer edges was carried as if on lit straw, a frequent vibration of weapons, skirmishing, and flight. Finally, a burning mountain of significant appearance, and surrounded by a constant halo, to progress from the sunrise toward the sunset with a movement very slow, and finally to be fixed in the region of the sunset. Unspeakable and too prodigious are the things that are recorded as having been seen after the middle of the night in the ether toward the Southeast, which, because I did not see them myself, being a little more fatigued and deceived by the empty interval of time, I would not want to recount here more widely. Although at that time the idea of slaughter was most openly published, and even the most atrocious conflicts, the sounds of arms, and drops of blood falling from the sky were confirmed by the consenting observation of many with one voice.

Epitasis.

Catastrophe.
