Findings and conclusions

Through this simple non-destructive study, a more detailed impression has been obtained on the paper selected by Andersen, Købke, Rørbye, Lundbye and Hansen for their

drawings and watercolour paintings in the first half of the 19th century. This was the Danish Golden Age, a period when new paper types became available such as wove and machine-made paper. Only limited numbers of 19th- and 20th-century watermarks have hitherto been published, and the documen-tation of 19th-century papers used by Danish artists in the first half of the century in Denmark, Norway and Italy will therefore contribute to knowledge on the production of, and trade in, paper made in Europe.

A study of European papers used for a selection of 18th-cen-tury architectural drawings at the Antiquarian Topographical Collection in the National Museum of Denmark revealed a dominance of Dutch laid paper.6 Laid papers from Danish paper mills were only represented in this group by writing paper used for letters and reports in connection with the buildings described. In a later study, the notes and dates writ-ten by Andersen on his 130 drawings from his grand tour revealed that relatively new Whatman wove paper must have been available in Italy. The notes and dates added by Hansen, Købke, Rørbye and Lundbye on their numerous drawings and watercolour paintings from their grand tours, and from Denmark and Norway, document that the new Whatman wove paper was available not only in Italy but also in Denmark during the first part of the 19th century. It is obvious that Martinus Rørbye, like the English artists Gainsborough, Downman and Turner,7 chose wove paper with a smooth vellum-like surface for his watercolour painting of the even-ing atmosphere in Procida, where the paper tone and texture was used in the painting as a colour in itself (Fig. 8). Rørbye’s watercolour paintings and pencil drawings illustrate how the tone and texture of the paper unite with the thin layer of paint to create the composition without the use of varnish. Such extremely fine details could never have been done so per-fectly on any type of paper other than wove, such as the one he used in his pencil drawing of Constantinople a few months later (Fig. 9). Rørbye only used coloured papers for drawings with pencil and chalk, whereas Hansen and Lundbye chose coloured papers not only for many of their drawings but also for watercolour paintings.

Dutch paper is still richly represented in the work of Andersen, Købke, Rørbye, Lundbye and Hansen – not only laid paper but also wove paper from C & I Honig’s mill (Fig.

10). All the papers without laid and chain lines or watermarks might be either handmade wove paper or machine-made paper, which have a similar appearance. Clear evidence for the difference in fibre direction between the randomly oriented fibres in handmade paper and the existence of a dominant fibre direction for machine-made paper was not possible to obtain in this non-destructive macroscopic examination.

The fragments of watermarks, observed in Andersen’s drawings from Florence, illustrate that these papers origi-nated from Italian paper mills. Examination of the paper of the last drawing from Florence in OBM’s collection con-firmed that it originated from Gaetano Amatruda’s paper mill in Amalfi (Fig. 11). Andersen had indeed bought and used Italian paper from one of the numerous paper mills in Valle dei Mulini in Amalfi, as had been anticipated at the beginning of the study. The Amatruda paper mill still exists and is now

ANNA-GRETHE RISCHEL

the only one left in Amalfi, where high-quality handmade drawing paper is produced today by Gaetano’s descendants, Teresa and Antoinetta Amatruda. Andersen also used hand-made French and other Italian papers for his sketches, some of them wove, such as Johannot’s papier velin from Annonay.

Without white rags of fine quality it was not possible to produce white paper for writing, printing and drawing.

Papermakers often added blue pigments such as smalt or blue fibres to produce a white paper. The presence of col-oured paper among the drawings and watercolour paintings at SMK could either illustrate a serious and growing scar-city of sufficient white rags for the production of white paper or a desire by the artists to use coloured paper other than the classical white drawing paper. Toned papers have always been used by artists for drawing with chalk, and drawings and watercolour paintings on coloured papers are well rep-resented among the works in the SMK collection (Fig. 12).

Much information can be found by simply studying the paper material with the naked eye, as illustrated by the print of the

French papermakers’ final check of paper sheets (Fig. 13) in Jérôme de La Lande’s book L’art de faire le papier of 1761.8 We should follow in their footsteps and continue to study paper to learn more of its history, technology and origin.

According to Hills: ‘The elder Didot, the noted Parisian prin-ter and publisher, regretted that it was not possible to print on laid paper with some of the fine type produced by the English type-founder Caslon, and sent a letter to Johannot, a skilled papermaker in Annonay. After studying the paper of Baskerville’s Virgil, he carried out some trial experiments with woven wire cloth and produced paper called papier velin.’ See also M.-H.
