Where 1064 fits
Why 1064 is special
Gold's low melting point relative to its durability is why it was worked before iron and why it survives from antiquity — it can be melted and recast indefinitely without degrading, so most ancient gold has been recycled many times.

- History
In 1064, Coimbra was taken by Ferdinand I, extending the Christian frontier to the Mondego (Iberia).
- Science
The melting point of pure gold is 1064 degrees Celsius. Low enough to have been worked with pre-industrial furnaces, which is a large part of why gold was among the first metals used. It is also a fixed point on the international temperature scale.

In historical numeral systems
Egyptian
1 lotus, 6 hobbles, 4 strokes
1 × 1,000 + 6 × 10 + 4 × 1 = 1,064. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 7 vertical wedges (sixties place), 4 corner wedges + 4 vertical wedges (units place)
17 × 60 + 44 = 1064. Places are separated by a space on the tablet, with the higher place written first.
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.

Related numbers & connections
1064 is a year in the 11th century, in the 1060s.
Gold melts around 1,064 degrees and iron at 1,538. Ancient furnaces reached the first and not the second, which is why gold was worked millennia before iron despite iron being far more abundant.

DocumentedScienceGeography: worldwideGold melts at a temperature ancient furnaces could reach and does not corrode, so it has been melted and recast continuously for millennia. Much of the gold in circulation has been through many earlier objects.

Common questions
Is 1064 a prime number?
No, 1064 is not prime.
What are the factors of 1064?
The factors of 1064 are 1, 2, 4, 7, 8, 14, 19, 28, 38, 56, 76, 133, 152, 266, 532, 1064.
What is 1064 in Roman numerals?
1064 in Roman numerals is MLXIV. IV is subtractive: one before five — five minus one. Written additively it would be MLXIIII, which Roman inscriptions used freely — the strict subtractive form is a later convention.
