Hans Ulrich Fisch

Hans Ulrich Fisch is identified, within a digital corpus devoted to seventeenth-century iconography, by an entry appearing in the «17th Century – Iconography» section of the Academic Bass Portal (f3, f6).

More specifically, the entry in question forms part of a body of material devoted to visual representations of bass instruments from the period (f6).

The name «Hans Ulrich Fisch» also appears on the Wikipedia page entitled «List of Swiss painters» (f1).

The same Wikipedia page identifies the German version of Wikipedia as the principal source for the entry concerned (f4).

These attestations thus bring together a mention in a list of painters and an inclusion in a specialised iconographic corpus on the seventeenth century, as presented in the documents provided (f1, f3, f6), with the German Wikipedia indicated as the principal reference (f4).

For documentary review, note the duality of the sources—an iconographic entry relating to seventeenth-century bass instruments (f3, f6) and a list entry on Wikipedia (f1)—as well as the indicated principal reference (f4), in order to guide any further verification.
