After his death, John Philoponus was declared to have held heretical views of the Trinity and was made anathema at the Third Council of Constantinople in 680–681. This limited the spread of his ideas in the following centuries, but in his own time and afterwards he was translated into Syriac and Arabic, and many of his works survived and were studied by the Arabs. Some of his works continued to circulate in Europe in Greek or Latin versions and influenced Bonaventure. The theory of impetus was taken up by Buridan in the 14th century.
