Tarsila is a Portuguese-Latin name from Tharsilla (martyred Roman virgin). Tarsila do Amaral (1886-1973) was the founding mother of Brazilian modernism — her 1928 painting Abaporu ("the man who eats") inspired her husband Oswald de Andrade's Anthropophagic Manifesto that defined modern Brazilian art.
Tarsila does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Tarsila reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
