# The first-voyage journal records scurvy and death on the long ocean legs

Date: 1498

## The fact

Hakluyt-English journal pages print swollen gums and deaths on the Atlantic and Indian Ocean legs.

It is one event.

## Context

Not a unique clinical trial. High confidence on scurvy as received in the journal.

[Vasco da Gama](/people/vasco-da-gama) Shared work with other named actors remains in the record.

Vasco da Gama’s documented role is bounded by other offices and collaborators named in the sources below. Sharing a field with them is not a reason to drop a documented act, and it is not a reason to assign later consequences done in the name after death.

Conventional years are c. 1460s–1524.

Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers are the surviving public file.

## Evidence and sources

A Journal of the First Voyage of Vasco da Gama — public English and Hakluyt Society — Journal of the First Voyage of Vasco da Gama independently describe this instrument.

Official or archival record: A Journal of the First Voyage of Vasco da Gama — public English (https://www.gutenberg.org/ebooks/22599; Project Gutenberg / Hakluyt translation).

## Significance

Printed scurvy is not a 1498 hospital chart.

## What is established and what is not

Established as a dated public record of this instrument.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Established here: a sourced, dated public instrument with a named contribution by Vasco da Gama.

They are not a public rating.

The driver `health-system-capacity` is attached because the mechanism named in Significance follows from this instrument, not because a standing list of welfare headings needed another tick. Vasco da Gama did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A portrait or conventional bust is not this mechanism. Allegation, reconstruction, and established occurrence stay distinct. Driver `health-system-capacity` is attached because the Significance sentence names a mechanism from The first-voyage journal records scurvy and death on the long ocean legs at 1498-01-01, not because a standing driver list needed coverage.
