   And to the ladyes he reſtored agayn / The bodyes of her huſbandes yͭ were ſlayn / To done obſequies as tho was the gyſe. And to the ladies he restored again / The bodies of their husbands that were slain / To do obsequies as then was the custom. 1478, Geoffrey Chaucer, The Canterbury Tales
   But, to-day, there were no obsequies to observe at all. 1919, Ronald Firbank, Valmouth, Duckworth, hardback edition, page 13
