A group of one thousand things is sometimes known, from Ancient Greek, as a chiliad.[1] A period of one thousand years may be known as a chiliad or, more often from Latin, as a millennium.
The number 1000 is also sometimes described as a short thousand in medieval contexts where it is necessary to distinguish the Germanic concept of 1200 as a long thousand.
