(3 syl.). A self-indulgent person; a wanton. The inhabitants of Sybaris, in South Italy, were proverbial for their luxurious living and self-indulgence. A tale is told by Seneca of a Sybarite who complained that he could not rest comfortably at night, and being asked why, replied, “He found a rose-leaf doubled under him, and it hurt him.” (See Ripaille.)
All is calm as would delight the heart Of Sybarite of old.
