encomium (n.)

"discriminating expression of approval, formal praise or laudation of a person or thing," 1580s, from Late Latin encomium, from Greek enkōmion (epos) "laudatory (ode) to a conquer or eulogy or panegyric on a living person," neuter of enkōmios "belonging to the praise or reward of a conqueror; proper to the Bacchic revel, in which the victor was led home in procession with music, dancing, and merriment," from en "in" (see en- (2)) + komos "banquet, procession, merrymaking" (see comedy).
