“ In Germany the triolet has attracted much attention. Those which had been written before his day were collected by Friedrich Rassmann, in 1815 and 1817. But as early as 1795 an anthology of triolets had been published at Halberstadt, and another at Brunswick in 1796. Rassmann distinguished three species of triolet, the legitimate form (which has been described above) , the loose triolet, which only approximately abides by the rules as to number of rhymes and lines, and single strophe poems which more or less accidentally approach the true triolet in character. ”
