“…They were produced either in Andalusian territory or within the Arab diaspora, possibly the latter. Until 2012, the manuscripts were stored in Timbuktu libraries [5][6][7][8][9] and are now preserved at the Timbuktu Andalusian Library (Biblioteca Andalusi de Tombuctu, Fondo Ka'ti), and its president, Ismael Diadié Haїdara, dated them [60]. In our first publication, we focused on the organic reds, proving unequivocally that lac dye was used in Islamic manuscripts for the first time and highlighting the richness and diversity of the paint formulations used, Fig.…”

“…At what temperature 20 ºC, 30 ºC, 40 ºC? It is this "science of use", which made these inks durable and endowed them with the highest possible performance, that we want to recover, and that is why we have been experimenting with these recipes for the last 4 years [42][43][44][45][46]. All steps, processes, weights and ingredients are described in the experimental section and Table 2.…”

The making of black inks in an Arabic treatise by al-Qalalūsī dated from the 13th c.: reproduction and characterisation of iron-gall ink recipes

For the first time, this paper systematises the medieval preparation of black writing inks found in the important thirteenth century Andalusian technical treatise written by Muhammad ibn Idrīs ibn al-Qalalūsī (1210–1308). We present the Arabic version of this extraordinary text (‘The gifts of the wise men on the curiosities of the substances’), and its first English translation, as well as discuss key aspects of the processes that remain missing or are unclear indications. In this work, we studied the iron gall inks based on galls, where no other phenolic source is present. In this pedagogical treatise, the recipes for these black iron-gall inks are organised and classified by the gallnuts extraction method used: boiling (decoction), squeezing and infusion, with water being the only solvent used. The inks selected were reproduced and characterised through a multi-analytical approach. Quantification was performed by HPLC–DAD (high performance liquid chromatography with diode array detectors in the UV–VIS), showing that gallic acid is a minor compound in the gall extracts prepared following al-Qalalūsī instructions. In all the recipes, the higher concentration compounds in the gall extracts are the gallotannins pentagalloylglucose and hexagalloylglucose, ranging from 79 to 50% of the phenolic compounds. This supports the results of Raman and infrared spectroscopies. A comparison with medieval Iberian recipes was also done, which served to reinforce our previous results that show water as the sole solvent extracts with much lower yields than mixed solvents (water plus white wine or vinegar).

“…Researchers use a variety of methods to analyze illuminated manuscripts, including: • Codicological analysis: They are based on the physical characteristics of the manuscripts, such as the materials used, the binding, and the scribal script [17]. • Paleographical analysis: They devise analysis based on the handwriting of the manuscripts to identify different scribes and to date the manuscripts [18]. • Machine learning based analysis: This type of analysis examines the visual aspects of the digital images associated with the medieval illuminations in order to facilitate their classification [19], [20].…”

Medieval illuminations represent a system of graphic and visual information, based on metaphorical relationships whose meanings and messages are determined in a specific and evolving context. We consider an illumination as a knowledge graph used by certain elites during the Middle Ages to symbolize their social identity and convey events from their lives, along with their cultural values. This knowledge graph contains a set of entities connected through semantic relationships and was used to encode metaphors and impactful messages that can sometimes be challenging for non-experts to decipher. Our aim is to provide a straightforward approach to decoding those messages. Therefore, we first consider medieval illuminations as images and use YOLOv3 to identify the objects inside a given image using bounding boxes. Moreover, we retrieve the entities from the image, their relationships, and the implicit messages using logical inference. The ultimate aim is to simplify the interpretation of illuminations and provide in the future privacy tools for contemporary social media, such as a logical framework for encoding and transmitting information.
