The Cambridge Geniza get a mention in Dr. Laura Nuvoloni’s project blog. Dr Esther-Miriam Wagner helped Laura decipher some Hebrew inscriptions she had found on the blank recto of the title page of the Cambridge University Library copy of the Anthologia Graeca Planudea (published by Janus Lascaris and printed by Laurentius (Francisci) de Alopa Venetus in Florence on 11 August 1494).
The inscription, “12 grozim Ingolstadt”, was written in Yiddish in a Hebrew hand and was datable to the end of the 15th century.
This small inscription provided Dr. Laura Nuvoloni with a price and the name of the German town in which the book was in at the end of the 15th or the beginning of the 16th century.
