Why do you suppose that there is little information about intelligence gathering in ancient Rome compared to today's intelligence methods?
O Military intelligence is a recent practice
The information from antiquity is probably contained in Latin and Greek languages
O Only scholars know about ancient spying
O Codes and ciphers were invented only recently

personally I'd say the information from antiquity is probably contained in Latin and Greek languages.

Explanation:

I say this is the answer because most people don't know how to translate Latin and Greek languages. so naturally most people would look at it and go "I have no idea what I'm looking at" and move on. so I think that it would be lack of knowing about Latin Greek languages

in which two ways were the northeast woodland indians and the southeast indians similar? both collaborated to form the iroquois confederacy. both cultivated the crops of corn, beans, and squash. both lived in rich environments of swamps and rivers. both lived in tree-bark dwellings called wigwams. both expected men to hunt, while women farmed.
