Galileo was a genius in his days but I would not write that
he was the first relativist. The reason being that the concept
of energy and its conservation seems self evident today, but
it was a novel idea as late as the 1850's and had eluded such
man as Galileo (1564 - 1642) and Newton (1642 - ??).
Poincare born in 1854 understood the concept of energy
and its conservation.

"His breakthroughs in mathematical astronomy were outlined in
three-volume treatise, "Les methodes nouvelles de la mecanique
celeste" (1892 - 1899), translated as "New Methods of Celestial
Mechanics" in 1993, the aim of which was, in Poincare own words,
"to ascertain whether Newton's law of gravitation sufficed to explain
all celestial phenomena" In 1906, in a paper on the dynamics of
the electron, he obtained, quite separately from Einstein many of the
results of the special theory of relativity."

Remember, that by 1904 Poincare had stated as a postulate,
the Principle of Relativity; and even went as far as to say that
"from all these results there must arise an entirely new kind of
dynamics, which will be characterized above all by the rule that
no velocity can exceed the velocity of light."
--------
All those facts point to Henri Poincare as the first "relativist."
