North is up on most of the maps that we see today.
The 2024 Total Solar Eclipse through the eyes of NASA Note that North is at the top
Older maps have East at the top :
The Hereford mappa mundi, a map of the world with Jerusalem at its centre Note that East is at the top.
However, South was popular too:
al-Idrisi world map in Arabic from ‘Alî ibn Hasan al-Hûfî al-Qâsimî’s 1456 copy, made at Cairo and now preserved at Oxford’s Bodleian Library as MS. Pococke 375 fol. 3v-4. According to the French National Library, “Ten copies of the Kitab Rujar [Book of Roger of Sicily; the Tabula Rogeriana] exist worldwide today. Of these ten, six contain at the start of the work a circular map of the world which is not mentioned in the text of al-Idris”. The original text dates to 1154.
Note that south is at the top of the map.
