James Tissot, Vinegar to Drink, Brooklyn Museum, 1884-96
Improperium expectavit cor meum et miseriam et sustinui qui simul mecum contristaretur et non fuit; consolatem me quaesivi, et non inveni et dederunt in escam meam fel et in siti mea potaverunt me aceto.
Thy rebuke hath broken my heart; I am full of heaviness. I looked for some to have pity on me but there was no man, neither found I any to comfort me. They gave me gall to eat, and when I was thirsty they gave me vinegar to drink.
In the traditional Roman Catholic Mass, Improperium was the Offertory chant for Palm Sunday.
