Overview

Clasina "Ina" Isings (15 February 1919 – 3 September 2018) was a Dutch classical archaeologist and museum curator whose scholarship centered on ancient glass and material culture. Born in Soest, Netherlands, she combined museum work with academic research and a long association with the University of Utrecht. She is widely remembered for careful typological studies and cataloguing that helped standardize how Roman glass finds are described and compared.

Career and museum work

From 1961 until 1995 Isings managed the collection of the Provincial Utrecht Society of Arts and Sciences (Provinciaal Utrechts Genootschap, PUG), where she curated objects, organized storage and documentation, and prepared material for study and display. Her institutional role required both conservational oversight and the creation of accessible catalogues for researchers and the public. In parallel she maintained links with academic colleagues at the University of Utrecht and contributed to teaching and local archaeological projects.

Throughout her career, Isings emphasized precise description and comparative classification. Her studies focused on the forms and production techniques of pottery and glass from antiquity, with particular attention to small finds such as vessels and lamps that are common in dated archaeological contexts. These typologies allowed excavators to date sites more reliably and to trace patterns of trade and manufacture across the Roman world.

Contributions and legacy

Isings published catalogues and research reports that became standard reference points for museum professionals and field archaeologists. Her approach—meticulous measurement, consistent terminology, and clear illustrations or descriptions—helped later generations of specialists communicate findings across language and regional boundaries. Collections she curated remain used for study and loan, and her classification schemes are still cited in archaeological literature.

Key themes in her work include:

  • Typology and classification of Roman glass forms;
  • Practical museum curation and cataloguing methods;
  • Bridging academic research and public collections to support field archaeology.

Isings retired to Bilthoven and died there on 3 September 2018 at the age of 99. For a concise overview of her professional life and bibliography, see a professional profile that summarizes her main publications and institutional roles.
