“Dear Colleague,

Thank you for RSVPing to our Conserving Canvas Zoom Presentation series. Our next presentation will be held this Thursday, July 8th at 9:00am PT (Los Angeles time). This is a very special presentation (outside of the Conserving Canvas grants) and very relevant to the paintings conservation field. Please be sure to join!

Presented by Helena Loermans, the talk is titled “Canvas: The Textile Layer in Paintings.” Helena is the founder of Lab O and a Dutch weaver working in Portugal. She will talk about her research and reconstruction of a-typical canvas patterns.

Please note that the presentation will be recorded (not including the Q&A) and that we use the same Zoom link for each presentation.

weave drafts of the canvases of the altar pieces of the Sanctuary of Our Lady of Charity, Illescas, provice of Toledo, 1603-7 and of the canvas of “View and Plan of Toledo” 1608

Note that the canvases are both woven on a loom with 14 shafts…

El Greco


Find the (almost invisible) differences in the pattern of the two canvases in the first row. The warp threads were threaded in the same design in the loom , the weaver skipped a few weft passes in each repeat. Not a mistake!

No connection in the lines of the patterns of the canvases of “The Vendramin 1540-45 Family” and “Isabella d’Este” 1536

Close examination of the weave drafts reveals the differences

I will soon publish about the connection in the pattern of a textile find in the Oxburg Hall restauration, stay tuned!

…seeing lines between a textile in The Oxburgh Hall Finds and a tablecloth pattern, painted by Titian …

…I could not be more grateful for coming accros this interesting lecture by Anna Forrest and The Warburg Institute from december 2020.

Textile finds are part of these discoveries.

At the Warburg Youtube page is written: “Anna Forrest (National Trust) examines how the recent discoveries at Oxburgh Hall shed light on the vibrant material culture of recusant Catholics at a time of persecution. As the Oxburgh Hall project is still in its early stages, this lecture presents a key opportunity to discover how curators go about analysing objects, and start to formulate conclusions, while a project is still evolving. Dr Tessa Murdoch from the Victoria and Albert Museum acts as respondent for this event.

Titian’s painting “The Supper at Emmaus” shows a tablecloth with a pattern.

In both analyses we only see the lines, I hope to receive higher quality pictures to analyse the textile piece that has been found recently in The Oxburgh Hall. An amazing story !!!
