# A Perceptual Geography of the Levante

What was the Levante associated with in 16th-century Florence?

# Introduction

The Levante is an elusive place. Usually defined in relation with–or in opposition to–another territory, its meaning has rarely been stable, evoking different geographies according to the place and time the term was used. Yet if an objective and accurate definition of the term is hard to articulate, one can still hope to draw a subjective map of the region, using as a basis the correlations existing within a given corpus of texts. In other words, what space could the Levante evoke to a specific group of readers?
In this post, I will show you how to use data from the Medici Archive Project’s MIA database to visualize the specific places with which the toponym was associated.

# The MIA database

The MIA database is a collaborative platform for scholars who wish to upload and share their own photographs of archival material from the State Archives of Florence. Over the past year, and under the patronage of the National Endowment for the Humanities, our team has photographed, transcribed, synthesized, and classified thousands of documents stored in avvisi section of the Mediceo del Principato archive in Florence. While our database was not primarily intended for statistical analysis, the metadata we made available can be still downloaded and used as datasets.

# The dataset

In this case, the dataset I created covers all the news from Levante from 1543 to 1566, that is to say, from the first avviso recorded in the archives to the year when Sultan Suleyman I dies. Here is a sample of the data I extracted from the server. Made of three columns, the data consist of a unique document number, a place name, and a date.

## Cleaning up the data

To visualize this data, we need to make it readable as a csv (comma separated values) dataset. We also need to convert the geographic information included here to a more “machine-friendly” format: GPS coordinates. Because the dataset contains hundreds of entries, we would rather automate this process. This can be achieved fairly quickly and quite accurately using pre-trained language models such as GPT-3, Bloom, or AI-21, to name but a few. This operation needs to be closely supervised, however, as pre-trained language models have a slight tendency to hallucinate.

# The Density Map.

A density map is a type of visualization that highlights the frequency with which a place is mentioned in a given dataset. This is especially useful for understanding not just the geographic scope of one’s data, but also its focal points. Which places on the map are more frequently mentioned? And which ones are more episodic? Where are the centers, and how far is the periphery? Where on the map is a reader’s attention most likely to be focused?

For the sake of this experiment–and since I was in a rush–I used one of Map Box’s APIs. However, many visualization libraries and Geographic Information Systems allow you to produce the same kind of density map.

# A Few Observations

The result is more of an impressionistic tableau than the accurate representation of a clearly definable concept, and that’s precisely what I like about this experiment. Indeed, while data science can be a powerful ally to the humanities, we don’t necessarily have to abide by its rules.

Another interesting aspect of this experiment, is that the map reveals a Levante that is completely integrated with the rest of Europe and the Mediterranean. It also highlights the centrality of Edirne in the political geography of the Ottoman Empire. Moreover, Spain’s most relevant city in the map is neither Madrid nor the Escorial, but Naples. Last but not the least, Islands and small city-states such as Ragusa seem to have in important role mediating between the different powers of the region.

# How to request data from MIA

Although MIA is an outstanding collaborative tool for researchers, the data it stores in its servers is not easily accessible. Its back-end, for example, is not published in public repositories. However, you can still obtain the data by registering to MIA and doing requests it to the server using python.

### Request

url = "https://mia.medici.org/Mia/json/de/advancedsearch/advancedSearchResults/0/90/docYear/asc/?isNewsFeedSearch=False"
headers = {'Content-type': 'application/json', 'Accept': '*/*'}


### Write response to file

with open('response.json', 'wb') as fd:
for chunk in r.iter_content(chunk_size=128):
fd.write(chunk)


### Open JSON

f = open('response.json', encoding="utf8")


### Return JSON object as a dictionary

json_complete = json.load(f)


### Select data from the JSON and print it in a CSV format

with open('results.csv', 'w', newline='') as csvfile:
fieldnames = ['documentId', 'placeCited', 'documentDate']
writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
for i in json_complete['data']:
if i['topics'] != None:
for x in i['topics']:
documentId=x['documentId']
placeCited=x['topicPlaceName']
year=i['date']['docYear']
month=i['date']['docMonth']
day=i['date']['docDay']
documentDate=str(year)+ "-" + str(month)+"-" + str(day)
writer.writerow({'documentId': documentId, 'placeCited': placeCited, 'documentDate': documentDate})


Once you have downloaded the results.csv file, you can proceed to cleanup the data as explained above.
