How Can You Visualize Coin Finds with Nomismata?

Nomismata Offers Four Visualization Options:

Nomismata provides users with four different ways to explore and analyze data, each suited to different research needs:

1. List
2. Map
3. Network
4. Chart

1. List – A Column-Based Overview

The List view presents a structured, column-based table of results. This format allows for:

• Quick reference to key attributes of each object (e.g., coin finds, locations, sources).
• Sorting and filtering options to refine results based on specific parameters.
• Direct access to individual records for further details.

This view is ideal for data management, textual analysis, and cataloging.

2. Map – Geographical Representation

The Map view enables users to visualize finds and mints geographically.

• Each object (coin finds, mints) is plotted on a map, allowing for spatial analysis.
• Different find types (hoards, single finds, foundation deposits, etc.) are represented with distinct colors.
• Users can filter results by period, issuing authority, or other attributes to observe trends over time.

This visualization is particularly useful for understanding the geographic distribution of numismatic data.

3. Network – Relationship Analysis

The Network view highlights connections between entities within the database.

• Coins, mints, issuing authorities, and findspots are linked based on historical relationships.
• It helps identify patterns in coin circulation, trade routes, and minting practices.
• Users can zoom in and out to explore macro and micro-level connections.

This is an essential tool for studying complex historical networks and their evolution over time.

Here we see, for the mint of Ravenna, the relationship between finds (hoard, single, grave…) and coinage (Byzantine, Ostrogothic, Late Roman, Imperial Roman).

4. Chart – Temporal Trends and Data Analysis

The Chart view allows for statistical and chronological analysis of numismatic data.

• Users can track changes over time, such as coin production trends or findspot distribution.
• Different attributes (e.g., hoards vs. single finds) can be compared visually.
• The interactive timeline helps researchers explore data dynamically.

This feature is particularly useful for quantitative analysis and historical interpretation.

Here we see the temporal distribution of coin finds in Nomismata based on their terminus post quem. The distribution is not symmetrical, and this asymmetry reflects both the Dark Age and the fact that the territorial extent of the Byzantine Empire was highly variable over its 11 centuries of history.

Choosing the Right Visualization

Depending on your research goals, Nomismata allows you to switch seamlessly between these views:

✔ List → Best for detailed records and textual queries
✔ Map → Best for spatial analysis and geolocation
✔ Network → Best for understanding connections between data
✔ Chart → Best for detecting chronological trends

Together, these visualization tools enhance the analytical potential of Nomismata, making it a versatile platform for numismatic research.
