when did the military start using dog tags
Dog tag The earliest mention of an identification tag for soldiers comes in Polyaenus (Stratagems 1.17) where the Spartans wrote their names on sticks tied to their left wrists. A type of dog tag ("signaculum"), was given to the Roman legionnaire at the moment of enrollment.[2] The legionnaire "signaculum" was a lead disk with a leather string, worn around the neck,[3] with the name of the recruit and the indication of the legion of which the recruit was part. This procedure, together with enrolment in the list of recruits, was made at the beginning of a four-month probatory period ("probatio"). The recruit got the military status only after the oath of allegiance ("sacramentum"), at the end of "probatio", meaning that from a legal point of view the "signaculum" was given to a subject who was no longer a civilian, but not yet in the military.
Man's best friend (phrase) Previous to the 19th century, breeds of dogs (other than lap dogs) were largely functional. They served for activities such as hunting, watching, and guarding, language describing the dog often reflected these positions within society. According to the Oxford English Dictionary, “In the oldest proverbs and phrases dogs are rarely depicted as faithful or as man’s best friend, but as vicious, ravening, or watchful.” Beginning in the 18th century, multiplying in the 19th and flourishing in the 20th century, language and attitudes towards dogs began to shift. Possibly, this societal shift can be attributed to discovery of the rabies vaccine in 1869.[2]
