Yes, nera is nigra.
And ooops I was wrong: the missing comet is called tenaculum (I will change in the text too).
Dykes in his translations of Bonatti call it coenaculum and translates as bowl, and the same I have in a comment to Grosseteste but I have another text (the original in Italian) and it is called Tongs.
Anyway this is from Dykes translation:
“is similar to the color of Mars and has beneath it a ray like the smoke under ashes; but not in an excessive way. It does not signify famine, but battles in which religious people engage themself beyond the degree to which they are competent. ”
In the Italian text (1500):
“The comet called Tongs means death of mean people, and old and religious ones, who are dressed in black: severity and coldness, and loss of grace and damage in kingdoms and laws. “

Hi Margherita,

The text above mentions 9 types of comet only goes on to give details about 8. What about the second type of comet referred at the start called ‘Tenacum’?

Also is ‘Nera’ referred to at the beginning the same as ‘Nigra’?
