Where 759 fits
Why 759 is special
Schubert completed two movements, lived another six years, and never returned to it, which makes the usual explanations unsatisfying.

In historical numeral systems
Egyptian
7 coils of rope, 5 hobbles, 9 strokes
7 × 100 + 5 × 10 + 9 × 1 = 759. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 2 vertical wedges (sixties place), 3 corner wedges + 9 vertical wedges (units place)
12 × 60 + 39 = 759. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then nu, then theta, marked as a numeral
psi-nu-theta + keraia
psi + nu + theta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then shin, then nun, then tet
tav-shin-nun-tet
tav (400) + shin (300) + nun (50) + tet (9) = 759, written in descending order.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

D. 759 consists of two completed movements and sketches for a third. Schubert lived a further six years without completing it, and no documented reason survives.
