Mathematician and musician,
Studying planets and primes,
Astronomer and theologian,
His name lies in the skies.
In his name are some sequences,
One is quite prestigious.
Another is a mere eight notes,
Although the last’s ambiguous.
Sequence # 1:
Sequence # 2:
Who is he, explain the sequences, and what is the alternate ending to sequence #2?
Prefer no partial answers please.
