Zichmni then attempts to attack Iceland. After finding it too well defended, he attacks seven islands along its eastern side: Bres, Talas, Broas, Iscant, Trans, Mimant, and Damberc. All of these islands are fictitious. An alternative interpretation finds that in transcribing the letters the Zeno brothers' descendant mistook a reference to "Estlanda" for "Islanda" or Iceland, thus accounting for both the presence of those superfluous islands off Iceland and the mysterious absence of an equal number of islands off of the Shetland Islands. Further evidence in support of this claim is the similarity of place names in the Zenos' "Islanda" to modern day Shetland, for instance the island of Bressay for "Bres" and Danaberg sound near Lerwick for "Damberc".
