A poet in this language depicted a youth who knocks over a brass kettle, ruining his planned tryst, in the comic poem “Trouble in a Tavern.” A female (15[1])erotic poet in this language responded to a predecessor’s “Poem to the Penis” in her own explicit (15[1])“Poem to the Vagina.” Poets in this language mastered the “twenty-four classical meters” to compete (-5[1])in a poetic festival that, according to a somewhat invented tradition, awarded expensive chairs to the winners. To aid their memory, storytellers in this language wrote (*) catalogs that grouped topics under headings like “the three obstructers of slaughter.” (10[1])Those “triads” appear alongside (10[2])stories in this language (10[1])in The Red Book of Hergest (10[2])and The White Book (10[1])of Rhydderch. For 10 points, name this language from which Lady Charlotte Guest translated the (10[1])Four Branches of the Mabinogi. ■END■ (10[1])
