# Lieutenant João Lyra — Through the Brazilian Wilderness character guide

> Lieutenant João Lyra in Through the Brazilian Wilderness by Theodore Roosevelt.

**Role:** supporting

**Also known as:** Lieutenant Lyra, Lyra, João

**First appearance:** 0005-i-the-start

## Snapshot

A Brazilian army lieutenant serving under Rondon, he is one of the officers Roosevelt singles out by name in the book's dedication.

## Who they are

Lyra belongs to Rondon's cadre of Brazilian officers — Amilcar, Mello, Lauriadó, and the doctor Cajazeira among them — whose surveying and discipline make the expedition possible. Roosevelt inscribes the book to them as 'Companions in Scientific Work and in the Exploration of the Wilderness,' placing them beside Rondon in his esteem. Their presence makes the journey a joint Brazilian-American enterprise rather than a presidential excursion, and their local knowledge is the quiet infrastructure beneath every mile the party gains.
