Poetry, p. 25, which is of similar structure, we find the doubling of the frons.
In the first place may be mentioned those which have parallel arrangement of rhymes, and in which the frons is isometrical.
They are, however, found already in Provenal poetry, and consist of the forehead (frons) and the tail or veer (cauda).
Here the frons is connected with the cauda, which recurs in each stanza as a kind of refrain, by means of concatenatio.
If the frons precedes the versus, the same distinctions, of course, are possible between the two chief parts.
Most of these stanzas admit of being looked upon as tripartite on account of the bipartite structure of the frons.
The shorter, Septenary part of the stanza represents the frons, the tail-rhyme stanza, the versus.
Those parts which lie on the outside of the posterior half of the eyes, between which the Frons and Vertex intervene.
In many stanzas the first and the last part (frons and cauda) are anisometrical.
Decipit / Frons prima multos—First appearances deceive many.
