Sigtuna amulet I
The Sigtuna amulet I or Sigtuna plate I (signum U Fv1933;134, also U Sl5 and S 5) is an 11th-century runic amulet found in 1931 in Sigtuna, Uppland. Description
The amulet is a copper plate, 82 mm long, 27.5-29mm wide and 0.9mm thick. It was discovered at a depth of c. 1.2 metres in the 'Granhäcken' block of the medieval city of Sigtuna in March 1931, together with pottery fragments and bone combs. Additional excavations of the site were undertaken later the same year, but did not reveal anything new of interest. Inscription

To that attach the íss-runes, these íss-runes, that you may stay where you are. May you be affected by (my) curses, monster! Pereswetoff-Morath 2019
As part of her dissertation "Viking-Age Runic Plates: Readings and Interpretations", Sofia Pereswetoff-Morath discusses this find. She offers the following interpretation:

Transliteration:
A1 þurs‿×‿sarriþu × þursa
 2 trutin fliu þu nu͡funtin is
B1 af þiʀ þriaʀ þraʀ ulf ×
 2 af þiʀ niu noþiʀ ulfr---

Runic Swedish normalization:
A Þurs sārriðu, þursa drōttinn! Flȳ þū nū! Fundinn es (þurs sārriðu þursa drōttinn ...)
B (H)af þēʀ þrīaʀ þrāʀ, ulf, (h)af þēʀ nīu nauðiʀ! Ulfʀ (h)æfiʀ þessi sēʀ auk es uniʀ ulfʀ. Niūt lyfia!English translation:
A Wound-fever's troll, lord of trolls! You flee now! Found is (the wound-fever's troll, lord of trolls ...)
B May three torments take you, wolf, may nine needs take you! The wolf takes these (torments and needs) and with these the wolf remains calm. Use the magic charm! Theories
The inscription has been noted to have striking similarities with other Viking-age runic healing-charms, such as the Canterbury formula, written in Scandinavian runes but found in an Anglo-Saxon manuscript. It reads:

kuril sarþuara far þu nu funtin is tu þur uigi þik ¶ þorsa trutin iuril sarþuara uiþr aþra uari ·Gyrils sārþvara far þū nū! Fundinn eʀ þū! Þōrr vīgi þik, þursa drōttinn, Gyrils sārþvara. Viðr aðravari.Gyrill's wound-tap, you go now! You are found! May Thor hallow you, lord of the trolls. Gyrill's wound-tap. Against pus in the veins (blood poisoning). The phrase 'nine needs' (niu noþiʀ) is attested in other instances of pagan magic, such as the inscription on the Danish Ribe healing-stick, the Icelandic poem Sigrdrífumál and spell-book Galdrabók.
