[All]: The figure illustrated here can be seen in the fragment as -i i- in þorði Iðja and/or -a o- in Iðja orða. It corresponds to the figure of hiatus which Donatus lists but does not explain. Hiatus is elaborated further in Hiberno-Latin commentaries, e.g. by Sedulius Scottus (CCCM 40B, 334): Hiatus sunt, sicuti diximus, cum similes uocales ac similiter longae collisam hiantemque structuram ‘Hiatus is, as we have said, when similar vowels of similar length make a clashed and gaping structure’.
