The day of rest  prescribed in the Ten Commandments is the seventh day
or the sabbath, derived from the Hebrew verb shabath  ("rested"), and which
is reflected in the name of the seventh day of the week in several of the
Romance languages -- e.g., Italian "Sabato."
Moreover, the name for the first day of the week in several of the Romance
languages is derived from the Latin Domini ("Lord") -- e.g., Italian
"Domenica."
As a matter of fact the names of the days of the week in Portuguese are
Domingo, Segunda-fiera, Terca-fiera, Quarta-fiera, Quinta-fiera,
Sexta-fiera, Sabado.

So... ISO notwithstanding, it's pretty clear from historical usage that
Sunday is
the first day of the week.
