<P> Roads allowed quick movement (on foot) for the Inca army and shelters called tambo and storage silos called qullqas were built one day's travelling distance from each other, so that an army on campaign could always be fed and rested . This can be seen in names of ruins such as Ollantay Tambo, or My Lord's Storehouse . These were set up so the Inca and his entourage would always have supplies (and possibly shelter) ready as they traveled . </P> <P> Chronicles and references from the 16th and 17th centuries support the idea of a banner . However, it represented the Inca (emperor), not the empire . </P> <P> Francisco López de Jerez wrote in 1534: </P> <P>... todos venían repartidos en sus escuadras con sus banderas y capitanes que los mandan, con tanto concierto como turcos . (... all of them came distributed into squads, with their flags and captains commanding them, as well - ordered as Turks .) </P>

What kind of environment did the incas live in
