I'm having trouble with quote but on December 8th Bowerthane said.
Oh, and are /mínútum/ and /secundum/ creative anachronisms or do you have a source for them?
I am reading Byrhtferth’s Enchridion and he deals with units of time. He has mīnūtum but for a time period of 6 minutes. For one minute he uses ostentum. He does not have a word for a second. His smallest unit is an atomos and there are six and four fifteenths atomos in a second. Did he have an atomic sundial?
His unit s are
376 atomos = 1 ostentum 1 minute
1.5 ostenta = 1 momentum
8/3 momenta = 1 dǣl
1.5 dǣlas = 1 mīnūtum
2.5 mīnūta = 1 prica
4 prica = 1 tīd 1 hour
6 tīda = 1fēorðling
4 fēorðlingas = 1 dæġ 1 day
It looks as though atomos is from Greek with ostentum, momentum and mīnūtum from Latin.
Byrhtferth dealt with most of this in the following magnificent sentence.
Se ān dæġ hæfð fēower and twentiġ tīda, and syx and hundnigontiġ prica, and mīnūta twa hundred and fēowertiġ, and þrēo hund dǣlas and syxtiġ, and momenta nigon hundred and syxtiġ, and ostenta ān þūsend and fēowertiġ and fēower hundred, and atomos fīf (hund) þūsend and fēowertiġ þūsend and ān þūsend and fēowertiġ and fēower hundred.
Byrhtferth missed out the “hund” in brackets.
