Lagu

Lagu's stanza reads the ocean as seeming interminable to men who venture out on the rolling bark, their ship, the waves of the sea terrifying them very greatly, a reading of open water that emphasises its fearsome vastness rather than the note of eventual safe arrival Sigel's own maritime stanza offers, water here left unresolved as pure threat rather than a hardship a returning sun eventually answers. This makes Lagu one of the more consistently difficult stanzas in the poem's later section, its fear stated without the qualification or eventual comfort that softens Nyd's reading of hardship or Rad's contrast of ease and difficulty, the sea simply terrifying and left at that.

Halsall's critical edition notes that this comparatively unrelieved difficulty fits a broader Anglo-Saxon literary wariness of the sea found across Old English poetry more widely, the ocean a genuinely dangerous, alien space in a culture whose settlement of Britain itself had required crossing it, so the fear the stanza names was not an abstract or merely poetic anxiety but one grounded in real, lived risk for anyone who actually had to make such a crossing. The stanza's wariness sits beside a simple historical fact worth stating plainly: the Anglo-Saxon settlement of Britain itself required exactly this kind of crossing, so the fear Lagu names was not abstract poetic colour but a hazard the culture's own founding journey had made real.

Lagu is the twenty first of the twenty four Futhorc runes carried from the Elder Futhark, its name and core reading a direct continuation of Laguz, whose own name likewise means water or the sea, both traditions naming the same element though, as with Mann's own case, the sparse Elder Futhark evidence gives no independent confirmation of whether the specifically fearful reading the Old English stanza offers reflects an older, shared association or a development particular to the Anglo-Saxon literary tradition's own well attested wariness of open water.

R. I. Page's account groups Lagu among the runes whose sound value, l, is among the most phonetically stable across every runic tradition's history, a liquid consonant that resisted the kind of sound change affecting some of the row's vowels and diphthongs. Lagu's position as the twenty first of twenty four inherited runes places it within the final stretch of signs shared with the Elder Futhark, only Ing, Ethel and Daeg remaining before the futhorc's five purely Anglo-Frisian additions extend the row beyond what the older continental and Scandinavian tradition ever recognised. Page notes Laguz's letterform as one of the simpler single stroke signs in the row, offering little scope for the kind of pictorial reading proposed for more visually distinctive runes such as Gebo or Ehwaz, its meaning resting entirely on the name rather than on any suggestive shape.
