=Twelve-lined stanzas= are much more frequently used, even in Middle English poetry; one of four-foot verses according to the scheme _a b a b a b a b b c b C_ (the stanzas being connected into groups by _concatenatio_) occurs in the fine fourteenth-century poem, _The Pearl_. Another of four-stressed verses corresponding to the formula _a b a b a b a b c d c d_ we have in Wright's _Polit. Songs_, p. 149; one of four-foot verses together with other forms of stanzas (_a b a b a b a b a b a b_, _a b a b c d c d e f e f_) we have in the poem on the _Childhood of Christ_ (ed. Horstmann, Heilbronn, 1878). But it is chiefly in Modern English poetry that stanzas of twelve lines are very common, especially stanzas consisting of three equal parts, with crossed rhymes. In some of these there is no difference at all in the structure of the three parts, as e.g. in a stanza by Prior (_Poets_, vii. 402) on the model _a b a b c d c d e f e f₄_; while in others the refrain (consisting of the four last verses) forms the _cauda_, as e.g. in Moore's _Song on the Birthday of Mrs. ----_: _Of all my happiest hours of joy, And even I have had my measure, When hearts were full, and ev'ry eye Hath kindled with the light of pleasure, An hour like this I ne'er was given, So full of friendship's purest blisses; Young Love himself looks down from heaven, To smile on such a day as this is. Then come, my friends, this hour improve, Let's feel as if we ne'er could sever; And may the birth of her we love Be thus with joy remember'd ever!_ Now and then certain modifications of this form of stanza are met with, especially stanzas the four-lined refrain of which forms not only the end, but also the beginning, of the stanza (but as a rule only in the first stanza, the others having the refrain only at the end); e.g. _A B A B c d c d A B A B₃_ (st. 1), _d e d e f g f g A B A B₃_. (st. 2), _h i h i k l k l A B A B₃_ (st. 3), in Moore, _Drink to her_. In other poems Moore uses this type of stanza with lines of four stresses, as in _Drink of this cup_, and with lines of two stresses, as in _When the Balaika_. For some rarely occurring stanzas of this kind see _Metrik_, ii, §§ 385, 386. A =stanza of thirteen lines= corresponding to the formula _a b a b b c b c d e e e d₄_ occurs in the Middle English poem _The Eleven Pains of Hell_ (E. E. T. S., 49, p. 210). Another one on the scheme _a ~ a ~ B c ~ c ~ B d ~ d ~ d ~ b e ~ e ~ B₃_ we have in Moore, _Go where glory waits thee_. As to stanzas of fifteen and eighteen lines see _Metrik_, ii, § 387.
