a sacred ornament worn on the head by bishops and certain abbots on solemn occasions; being a sort of cap, pointed and cleft at top. The high-priest among the Jews wore a mitre or bonnet on his head. The inferior priests of the same nation had likewise their mitres; but in what respect they differed from that of the high priest, is uncertain. Some contend that the ancient bishops wore mitres; but this is by no means certain.
