Analysis of Cologne

In Köhln, a town of monks and bones,
     And pavements fang'd with murderous stones
     And rags, and hags, and hideous wenches ;
     I counted two and seventy stenches,
     All well defined, and several stinks !
     Ye Nymphs that reign o'er sewers and sinks,
     The river Rhine, it is well known,
     Doth wash your city of Cologne ;
But tell me, Nymphs, what power divine
Shall henceforth wash the river Rhine ?
