Overview

Medieval Encyclopedia Entry 1779698584 refers to a single, meticulously illustrated folio (ff. 112r–113v) preserved in the Biblioteca Nazionale Marciana, Venice. The folio constitutes entry number 1779698584 in the modern Index of Medieval Encyclopedic Manuscripts (IMEM), a digital catalogue compiled by the International Society for Medieval Studies. The entry itself is a concise treatise on the “Four Classical Elements” (earth, water, air, fire) and their interrelation with the medieval concept of the quattuor humores (the four bodily humors). Rendered in Latin, the text combines excerpts from Aristotle’s De Caelo and De Anima with commentary by the 13th‑century scholastic, Thomas of Erfurt, illustrating the dynamic dialogue between ancient philosophy and medieval theology.

The folio’s illumination, executed in the vibrant Venetian style of the late 1200s, features a central diagram of the elements arranged in a tetrahedral schema, surrounded by marginalia depicting allegorical figures—Terra, Aqua, Aer, and Ignis—each accompanied by a brief Latin gloss. This visual‑textual synthesis exemplifies the medieval encyclopedic ambition to render complex knowledge both comprehensible and aesthetically resonant for monastic scholars and lay readers alike.

Entry 1779698584 occupies a pivotal position within the Speculum Universale, a compendium intended to “reflect the whole of learned knowledge” (speculum universale). As the 1,779,698,584th entry in the IMEM database, it serves as a reference point for scholars tracing the diffusion of Aristotelian natural philosophy into the scholastic curricula of the High Middle Ages, as well as for art historians examining the interplay of text and image in manuscript culture.

History/Background

The Speculum Universale was commissioned around 1272 by the Dominican convent of San Nicolò in Padua, under the patronage of the Venetian nobleman Marco Gradenigo. Its compilation was overseen by the Dominican scholar‑theologian Thomas of Erfurt (c. 1240–c. 1305), who sought to reconcile the rediscovered works of Aristotle with the doctrinal framework of the Catholic Church. Entry 1779698584 was drafted circa 1275, drawing directly from Thomas’s lecture notes on natural philosophy and from a now‑lost commentary on Aristotle’s Meteorologica.

The folio entered the Marciana collection in 1623, acquired from the private library of the Venetian patrician family Contarini. Its identification as entry 1779698584 resulted from the 1998 digitisation project led by Dr. Elena Bianchi, which assigned a unique identifier to each distinct encyclopedic entry across the corpus of medieval reference works. The IMEM system, launched in 2004, uses these identifiers to facilitate cross‑manuscript comparison, enabling scholars to locate parallel passages in other encyclopedias such as the Liber Floridus (c. 1120) and the Margarita Philosophica (c. 1500).

Key dates:
- c. 1275 – Composition of the entry by Thomas of Erfurt.
- 1623 – Acquisition by the Biblioteca Nazionale Marciana.
- 1998 – Digitisation and assignment of IMEM identifier 1779698584.
- 2004 – Integration into the International Index of Medieval Encyclopedic Manuscripts.

Key Information

- Authorship: Primarily Thomas of Erfurt, with later marginal glosses by an anonymous Venetian illuminator. - Content: A synthesis of Aristotelian elemental theory, the humoral model of medicine, and theological reflections on creation. - Structure: Latin prose (≈ 250 words) flanked by a central tetrahedral diagram and four marginal allegorical figures, each labeled with a one‑line gloss. - Manuscript Details: Folio size 22 × 15 cm; vellum base; pigments include ultramarine, vermilion, and gold leaf. - Transmission: The entry was copied in at least three other extant manuscripts (e.g., MS BAV 149, MS Paris Bibliothèque Mazarine 138) indicating its pedagogical popularity. - Scholarly Use: Frequently cited in studies of medieval natural philosophy, the reception of Aristotle, and the visual representation of scientific concepts in manuscript art.

Significance

Entry 1779698584 epitomises the medieval encyclopedic project: the ambition to codify, harmonise, and disseminate the totality of knowledge within a single, accessible format. Its blend of textual exposition and visual diagram anticipates later scientific illustration, marking a transitional moment when abstract philosophical ideas began to be rendered in concrete, pedagogical imagery. The entry’s survival across multiple copies underscores its utility in monastic curricula, where it functioned as a teaching aid for novices learning the foundations of natural philosophy and medicine.

Moreover, the entry illuminates the intellectual currents of the 13th century, a period often termed the “Aristotelian Revival.” By integrating Aristotle’s elemental theory with the humoral doctrine, Thomas of Erfurt demonstrates how medieval scholars negotiated the tension between pagan philosophy and Christian doctrine, a negotiation that would shape the trajectory of European thought up to the Renaissance. The folio’s artistic qualities also contribute to our understanding of Venetian manuscript illumination, reflecting a regional aesthetic that prized vivid colour and allegorical richness.

In contemporary scholarship, the IMEM identifier 1779698584 facilitates interdisciplinary research, linking textual analysis, codicology, and digital humanities. It serves as a case study in the benefits of systematic cataloguing for medieval studies, enabling scholars to trace the diffusion of specific ideas across geographic and temporal boundaries. As such, the entry not only preserves a fragment of medieval intellectual history but also exemplifies modern methodological advances in the field.
