On the Mosaic of the Main Porch of San Marco in Venice: Towards a Multi-Methodological Approach to Mosaics Study.
Bibliographic record
Abstract
After large contributions made by Otto Demus and Renato Polacco, the inner porch of San Marco was rigorously studied, but only single elements of its complex structure were taken into consideration. Scholars have agreed neither on the chronological sequence of the rows which compose the portal, nor on the original portal decoration. The formal analysis of the mosaic decoration has been implemented to clarify the chronological sequence of the Byzantine ateliers from the second half of the 11th century to the early 12th century. Other researches made a new statement regarding the doors that arrived in Venice between the last quarter of the 11th century and the beginning of the 12th century, one of them actually in use in the main portal. Many questions still remain. Was the portal structure originally made of three tiers or four (counting also the hypothetical vault demolished in the 16th century in order to open the light well called “pozzo”)? Are the di erences in quality of painting of the same tier due to restorations or to a di erent approach used in the images of different saints? Was there more than one artist involved in the process? There are also a lot of questions about the original door of the porch. The actual door of the main porch opening was offered by Leo da Molino († 1138), Procuratore di rispetto of the church of San Marco in the year 1112. It should be dated 10 to 30 years later than the portal, if we accept that the first phase of the porch was completed in the last quarter of the 11th century. The author reconsiders the recent studies of the main porch of San Marco drawing on an integrated approach. An attempt has been made to clarify the chronological phases of the architectural structure by using techniques like Geophysical prospections, analyzing glass materials, mapping different restorations and confronting the data of the multispectral analysis with the documents conserved in the archives of the Procuratoria di San Marco. e goal of the research is to study the mosaic within its structural, material, devotional, and ideological context trying to give the answers to all newly opened questions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
