This catalogue entry appears to refer to Angelo Mercuriali, here preserved under the related product-tag spelling “Angelo Mercurialli.”

It is attached to Callas’s 1953 La Scala recording of Bellini’s I puritani, with Giuseppe di Stefano, Nicola Rossi-Lemeni, Rolando Panerai and Tullio Serafin.

Because the catalogue uses variant spellings and the wider public trail is limited, this entry is kept as a cautious spelling-form marker rather than a separate full biography.

This page keeps the Callas-Bellini strand navigable without pretending to more certainty than the tag evidence allows.
