Rivers of Paradise
Rivers of Paradise (also The four Rivers of Paradise) are the four rivers described in Genesys 2:10-14, where an unnamed stream flowing out of Garden of Eden splits into four branches: Pishon, Gihon, Hiddekel (Tigris), and Phrath (Euphrates). These four rivers form a feature of the Garden that is popular in the Abrahamic religions. Geography. Although some commentators dismiss the geographic attribution for the Garden of Eden entirely, a considerable amount of research was done on matching the rivers in the Genesis to the real ones, on the premise that the Garden was "obviously a geographic  reality" to a writer of the Genesis verse (as well as his source), and thus dismissing the physical placement of the rivers is the contribution of the interpreters. To the second group of scholars, attribution of Euphrates is without a doubt, most of them agree on the Tigris (Hiddekel), but the identification of Pishon and Gihon is ambiguous. For religious scholars, a natural question "how did the heavenly rivers come to the Earth?" arises; various answers had been provided in the past. Christianity. Following Saint Ambrose (per Cohen, the association was established earlier, in a letter by Cyprian in 256  AD) the rivers are interpreted as four evangelists (or Gospels), with Water of Life flowing from the word of Christ (the Fountain of Life) to bring salvation. In Gospel manuscripts the connection was made either in the tituli (cf. St Gauzelin Gospels, Gospels of Lothair) or as an illustration (Vivian Bible). By the 11th century (Uta Codex) through a long chain of exegesis Gihon was personified as Matthew (and associated with happiness), Tigris as Mark (swiftness), Euphrates as Luke (fertility), Pishon as John (inspiration). Pseudo-Jerome's commentary on the Gospels (7th century) contains different associations with evangelists as well  as other quadruples, including the four elements and cardinal virtues. The four rivers or Paradise were frequently used in Christian art in 4th to 6th centuries AD (and later through medieval times, especially during the Carolingian period) in multiple allegorical meanings. In visual arts the rivers usually flow underneath Christ's feet or from His throne (cf. apse mosaics in Santa Costanza, Santi Cosma e Damiano, Santa Prassede, Santa Pudenziana, San Clemente al Laterano, Archbasilica of Saint John Lateran, Basilica of San Vitale). Two stags are occasionally depicted drinking from the streams, referring to Psalm 42: "As a deer longs  for flowing streams, so my soul longs for you, O God". On the North portal of Cathedral of Chartres the rivers are depicted as young men carrying vessels with outflowing water. Judaism. The rabbinic tradition does not interpret rivers literally, instead, they are believed to represent honey, milk, balsam, and wine. Genesis Rabbah identifies the rivers as four corners of the world: Pishon as Babylonia, Gihon as Media, Hiddekel as Greece, Euphrates as Rome. It also states that all waters in the world flow from the foot of the Tree of Life. Islam. Similarly to Judaism, Islam treats the rivers  of Paradise as carrying the honey, milk, water, and wine (cf. Q 47:15). However, Hosseinizadeh remarks that these are not the same rivers as in the Bible, since there are four "types" of rivers, not four "rivers" in this verse. Furthermore, there are more types discussed elsewhere in Quran (cf. Q 76:5-6 and Salsabil in Q 76:17-18), so there is no significant relationship between the biblical rivers of Paradise and the ones in Quran. The four rivers similar to the ones in Genesis can be found in hadiths. A hadith from Prophet Muhammad reports that four rivers emerge  from heaven: Euphrates, Nile, "Sayhān" and "Jayhān"; Hosseinizadeh stresses that the latter two are not necessarily "Sayhūn" (Syr Daria) and "Jayhūn" (Amu Daria). In a hadith narrated by Ibn Abbas Tigris is also included into the rivers of Paradise, "Sayhūn" is identified as Hinds, "Jayhūn" as Balkh. In the hadith of Mi'raj Muhammad witnesses four rivers of water, milk, wine and honey flowing from the base of the Sidrat al-Muntaha tree. Hunt draws parallels between the rivers of Paradise and the Persian "Charbagh" garden design.
