Alonso Sánchez Coello and El Greco both used a support canvas with the same woven pattern …

Infanta Isabel Clara Eugenia and Madalena Ruiz ; Alonso Sánchez Coello (1585-1588)

and

The Burial of the Count of Orgaz ; El Greco (1586-1588)

are both painted on a support canvas with the same woven pattern

The weave draft is interesting because of half of the repeat is threaded in 12 shafts while the other half in 11 shafts.

O Alonso Sánchez Coello viveu em Portugal.A obra “Infanta Isabel Clara Eugénia com Magdalena Ruiz” é sobre uma tela suporte com padrão complexo tecido. Analises no Lab O revelaram que é o mesmo padrão do que a tela suporte da tela “The Burial of the Count of Orgaz”; El Greco.Ambas pintadas nos anos 1585-88.Coincidência?

“Venha descobrir a OBRA CONVIDADA “Infanta Isabel Clara Eugénia com Magdalena Ruiz” de Alonso Sánchez Coello que pertence ao Museo Nacional del Prado, Madrid. Em exposição na sala 60/Galeria de Pintura Europeia até 2 de janeiro de 2022.Esta obra integra-se na tradição do retrato de corte criado em meados do século XVI, seguindo o modelo definido por Anthonis Mor, ao representar os membros da Casa de Áustria, e adaptado na Península Ibérica por Alonso Sánchez Coello.Nascido perto de Valência, Coello mudou-se com a família para Portugal, onde iniciou a sua educação artística. D. João III custeou, em 1550, a sua viagem à Flandres, onde foi discípulo de Anthonis Mor. Ao regressar a Lisboa, c. 1552, trabalhou para o príncipe D. João e para a sua mulher, D. Joana, irmã de Filipe II, que, quando enviuvou, regressou a Espanha. Em 1555, Sánchez Coello levou-lhe à corte, em Valladolid, um retrato do seu filho, o futuro rei D. Sebastião. O pintor não regressaria já a terras lusas.A figura da infanta, com uma das mãos apoiada na cabeça de Magdalena Ruiz, remete para outros retratos femininos da dinastia dos Habsburgos. A inclusão da imagem paterna – um retrato dentro do retrato, reproduzindo o busto em alabastro de Pompeo Leoni – servia para reforçar o porte majestático do modelo. A presença da anciã – uma criada muito próxima, vinculada à corte espanhola durante o reinado de Carlos V e de Isabel de Portugal – é igualmente um elemento que reforça o sentido da tradição e da continuidade familiar.A composição revela, por outro lado, curiosas referências filoportuguesas: a infanta exibe uma indumentária com as cores do cerimonial luso (ouro sobre branco) e Magdalena Ruiz – que, em 1581, acompanhara Filipe II a Portugal – ostenta, por sua vez, um colar de coral – eventual recordação dessa viagem – e sustém entre as mãos dois pequenos macacos, oriundos da América amazónica.”

analyses of the pattern of a 16th century painting from The Prado Museum

… the analyses of the X-ray image and trying to find how the threads were organised before this support canvas was woven in the 16th century was not easy!

Drawing the lines in colour on top of the xray makes each thread visible, both in horizontal and vertical direction.

These lines on square paper allow us to define the position of vertical threads in the shafts of a loom and how the horizontal threads were woven.

In this way, manually, I search the repeat of a pattern.

Spending much ‘puzzle’ time is also because I have until date not yet found a ‘partner in analyses of xray images’

The above analysis is of the pattern in the support canvas of the ‘obra convidada’ Museu Nacional de Arte Antiga, de Alonso Sanchez Coello ” Infanta Isabel Clara Eugénia com Magdalena Ruiz “

I have finisehd my essay with this quote:

“The project shows that innovative research can be done in a local workshop in a rural area provided it has an internet connection, support from conservators, authorization from museum departments for sharing information, and a loom.”

“Deciphering the Textile Layer of Historic Paintings”

DESCRIPTION
Textiles with a complex woven pattern were used as painters’ canvases by Italian and Spanish painters throughout the 16th and 17th centuries. The X-Ray technology reveals these patterns in the paintings and allows us to follow the position of each thread in the textile, both horizontally and vertically. Drawing all crossing points identifies the repeat of the pattern and a weave draft can be generated from this. Reconstructions have been woven in linen on a handloom. The presentation will guide you through the story of this project.
ABOUT THE PRESENTER
Helena Loermans is a former laboratory technician, engaged in histochemical and morphometrical investigation of normal- and pathologic muscle in the mouse, (Nijmegen University, The Netherlands) and is now weaving in her studio in Odemira. Lab O is a laboratory for the research and reconstruction of canvases of old master paintings. Its mission is: Recovering and sharing the knowledge of historic canvases. Loermans studied Jacquard Design in Florence, including textile analysis. She has a long term experience as a fine production weaver and as a weaving teacher and tutor in various European funded projects for Rural Development, Projects on Reintegration in Society as well as for adults with limited capacities.

upcoming presentation ICCOM-CC Paintings Working Group

announcement :

Helena Loermans Owner of Lab O, Portugal.

The Textile Layer of Paintings.

Helena Loermans will share how she has approached reconstructing different textiles used by painters as canvas.

Helena has used technical studies and x-radiograph images to reconstruct weave patterns in order to re-create them.

While art historians and paintings conservators have meticulously studied the paintings of the Old Masters, Helena has found there is a comparative lack of information on the characteristics of the canvas itself as a textile.

Helena has recently presented her approach to studying historic canvases at the Conserving Canvas symposium at Yale and to participants in the Conserving Canvas Initiative of the Getty Foundation.”

…sharing the knowledge in 2021:

Zoom presentations have been a great opportunity to share the research at

Lab O on the historic canvases and textile fragments located in the museums:

Conserving Canvas Zoom Presentations series:

8th July 2021

email announcement by The Getty Foundation::

“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.
