French liturgical poet of the first half of the thirteenth century. He wrote: (1) a series of poems to be recited on the seventh evening of Passover, some of which are arranged in alphabetical order; (2) a dirge beginning "?iyyon ?efirat pe'er," giving at the end in an acrostic "Me�r ?aza?"; (3) an alphabetical introduction to the Targum of Exodus 13:21, a passage which is read on the seventh day of Passover. The last-named poem is composed of six strophes, of four verses each, beginning with "It ?azuta we-dugma." According to Landshuth ("'Ammude ha-'Abodah," p. 159), Me�r was the author of the dirge beginning "A?birah millin," which is recited on the Ninth of Ab; but Zunz ("Literaturgesch." p. 360; Supplement, p. 38) ascribes it to Me�r of Rothenburg (comp. ib. p. 469).
