High resolution (R~20,000), high signal-to-noise (S/N~100) spectra were\ncollected for ~40 symbiotic stars with the Asiago echelle spectrograph over the\nsame 8480-8740 Ang wavelength range covered by the ESA Cornerstone mission\nGAIA, centered on the near-IR CaII triplet and the head of the Paschen series.\nA large number (~140) of cool MKK giant and supergiant templates were observed\nwith the same instrumentation to serve as a reference and classification grid.\nThe spectra offer bright prospects in classifying and addressing the nature of\nthe cool component of symbiotic stars (deriving T(eff), log g, [Fe/H],\n[alpha/Fe], V(rot)sin i both via MDM-like methods and syntetic atmosphere\nmodeling) and mapping the physical condition and kinematics of the gas regions\nresponsible for the emission lines.\n
