A famous madiæval hymn on the last judgment, probably the composition of Thomas of Celano, a native of Abruzzi, who died in 1255. Sir Walter Scott has introduced the former part of it into his Lay of the Last Minstrel.
Dies iræ, dies illa, Solvet sæclum in favilla, Teste David cum Sibylla.
On that day, that wrathful day,
David and the Sibyl say,
Heaven and earth shall melt away.
E. C. B.
