Ottoman and Venice: The Printing Ledger
Press by press and shelf by shelf
Same century, same science, same instruments. One jurisdiction had exit and the other did not. The book keeps the observatory story, Venice’s presses and the year 1727; here is the rest of the ledger.
Supports Chapter 12, “The Flight of the Dragon.” The printed book points here for the detail it no longer carries.
Two observatories
| Observatory | Opened | How long it ran | What came of it |
|---|---|---|---|
| Uraniborg, Denmark (Tycho Brahe) | 1576 | Roughly twenty-one years, under multiple patrons | The observational data Kepler used to derive the laws of planetary motion |
| Istanbul (Taqi al-Din, with the sultan’s backing) | 1577 | Three years; demolished by state order on January 22, 1580 | Torn down after the chief mufti declared it an affront to God |
Presses
| Where | Measure | Count |
|---|---|---|
| Venice | Printing presses in operation by 1500 | 150 to 200 |
| Ottoman Empire | First year Arabic-script printing was permitted | 1727 |
| The gap | Years between the Latin West’s presses and the first Ottoman Arabic-script press | Roughly 272 |
| Ibrahim Muteferrika’s press | Titles produced before his death in 1745 | Roughly 17 |
For roughly 272 years the entire Latin West was compounding on Gutenberg’s invention while the Ottoman scribal class copied manuscripts by hand. Muteferrika’s press produced a handful of titles and died with him. The gate was about the sacred script, not the technology: Chapter 15 records that Hebrew printing operated in Istanbul from 1493, more than two centuries before a press was permitted to work in Arabic script.
Checking in progress. The book gives the length of the printing gap in more than one way across chapters (roughly 272 years here, measured from the Latin presses; more than two centuries in Chapter 15, measured from Istanbul’s first Hebrew press in 1493). Both are arithmetic on the same endpoint, 1727.
Shelves
| Collection | Holding |
|---|---|
| Vatican Library, 1481 inventory | 3,498 manuscripts |
| Topkapi Palace | Roughly 120 non-Islamic manuscripts |
The two counts are not the same kind of measure: one is a library’s whole manuscript inventory, the other is only its non-Islamic holdings. They are set side by side as the book’s earlier edition set them, and read best as a picture of what each court chose to shelve from outside its own tradition.
