Jacob Grimm proposed that Zisa might be the consort of the god
Tyr (in
Old High German,
Ziu). Grimm also suggested a connection between Zisa and the
"Isis" of the Suebi attested by
Tacitus in his 1st century CE work
Germania based on the similarity of their names. Grimm's connection of Zisa to Isis may have been influenced by similar considerations made by humanists such as
Konrad Peutinger. The existence of a goddess Zisa was controversial through the nineteenth and early twentieth centuries. In 1936, R. Kohl critically examined the evidence for the goddess's existence: he determined that none of the archaeological or pictorial depictions that were said to depict Zisa in fact depicted the goddess. Examining the
Excerptum, Kohl argued that the name of the goddess seemed to have been derived as an explanation for the place name
Cisenberg, after which the "old name" for Augsburg,
Cisaris, was invented by the writer of the
Excerptum from
Cisae ara (altar of Cisa in Latin). Kohl argues that the name
Cisenberg can be explained without the goddess; alternative explanations are that it means "mountain on which
siskins [German
Zeisige] nest" or "mountain in the form of a breast" (German
Zitze). As all other information on Zisa appears to derive from the
Excerptum in one way or another, Kohl concludes that the goddess never existed. Following Kohl,
Rudolf Simek writes: (Cisa, Zisa) is supposedly the name of a Germanic goddess who, according to a Latin historical text from the 11th century, was worshipped in Augsburg in heathen times. While Grimm made extensive speculations about the identity of this goddess, today the supposition of a goddess Cisa is rejected because the source text does not stand up to critical examination. ==Notes==
