Type: supporting argument (off-timeline) · Assessment: sound — the Greek romance was translated and reworked from the Georgian Balavariani by Euthymius the Athonite (the Georgian monk of Iviron, d. 1028), not composed by John of Damascus (d. c. 749); the Damascene ascription is a later scribal guess enshrined by the martyrologies and standard editions, and modern critical scholarship — above all Robert Volk’s edition — treats Euthymius’s authorship as settled and the Damascene attribution as spurium. The residue of live debate is narrow: whether Euthymius composed the Greek himself or had it made at his instance, and how much he translated versus freely elaborated — not whether he, rather than the Damascene, stands behind it.
This page weighs the interpretation that the Greek Barlaam and Ioasaph — the fountainhead from which every later European telling descends — is the work of Euthymius the Athonite (Euthymius the Iberian/Georgian, c. 955–1028), rendered and elaborated from the Georgian Balavariani around the 980s, and that its long-standing ascription to the eighth-century theologian John of Damascus is false. The stakes for the timeline are chronological: if the Damascene wrote it, the Christian romance would be pushed back to the early eighth century and its Georgian parent obscured; if Euthymius made it, the tale became Greek and fully Christian only around the turn of the millennium, downstream of the Georgian Christianization — which is where the documented text-chain actually places it.
The traditional ascription was not arbitrary. Most Greek manuscripts head the work as brought “by John the Monk (an honourable man and a virtuous, of the monastery of Saint Sabas).” That Sabaite tag is a real hook: the most celebrated monk of Mar Saba named John is John of Damascus, so later scribes and editors naturally read “John the Monk of St Sabas” as him.1 The romance also looks Damascene: it is a doctrinally sophisticated Byzantine work, its hero catechized through long orthodox discourses (Barlaam’s teaching even embeds the second-century Apology of Aristides), the sort of theological freight a great dogmatician might be thought to carry. Once the identification was made it self-perpetuated: it was written into the Roman Martyrology under Sixtus V and printed on the title-page of the standard Loeb edition of 1914, which still issues the work under the Damascene’s name. A reader met the attribution as established fact at every turn. Historically, three candidates were “at present current”: John of Damascus (d. c. 749), an anonymous author around 600, and Euthymius (d. 1028); the “of St Sabas” line also fed a rival identification with John the Sabaite rather than the Damascene.1
The Greek depends on the Georgian, which the Damascene could not have used. The decisive turn came with the recovery of the Georgian Balavariani. The Greek Barlaam and Ioasaph is not an independent composition but a translation-and-elaboration of that Georgian text — the name-forms (Georgian Iodasaph → Greek Ioasaph; Balahvar → Barlaam), the plot, and the sequence all descend through the Georgian stage. An eighth-century Damascus writer, working before the Georgian Christianized version existed in the form the Greek presupposes, simply cannot be its source; the direction of dependence points to a Georgian translator working after the Balavariani.2
The external Georgian testimony names Euthymius. Euthymius the Athonite was the most prolific Georgian–Greek and Greek–Georgian translator of his age at the Iviron monastery on Mount Athos. His near-contemporary Georgian biography — the Life of John and Euthymius written by his successor George the Athonite (Giorgi Mtatsmindeli, c. 1045) — enumerates his translations, and the Balahvar romance stands among the works he turned from Georgian into Greek. This is direct, roughly contemporary attestation of exactly the transfer the textual evidence requires: a named Georgian monk of Athos rendering the Georgian tale into Greek around the 980s. It also explains the anomalous embedded Apology of Aristides, a Greek insertion characteristic of Euthymius’s learned, expansive method.3
The critical edition treats the question as closed. Robert Volk’s two-volume critical edition of the Greek text — issued, pointedly, within the collected Schriften des Johannes von Damaskos so as to adjudicate the authorship — opens with a magisterial survey of the whole history of theories and concludes that the ascription to Euthymius the Georgian has become “unavoidable,” classing Barlaam and Ioasaph among the Damascene’s spuria. That is now the standard verdict.4
What holds. The negative half of the claim — that John of Damascus did not write it — is as secure as such attributions get: the Greek presupposes a Georgian source that postdates him, and the manuscript “John the Monk” was only later, and speculatively, identified as the Damascene. The positive half — that Euthymius is the responsible figure — is supported from three independent directions (the Georgian textual dependency, the near-contemporary Georgian vita naming him, and the internal Byzantine-Georgian features such as the Aristides insertion) and is the settled scholarly consensus.
What remains genuinely open. Two finer questions are still debated, and neither unseats the claim. (1) Author or commissioner? The colophon of the Iviron tradition can be read as saying the Greek was made by Euthymius (hypó) or merely at/through him (pará / hypér Euthymíou) — i.e. produced at his instance rather than wholly by his own hand; the grammatical point has its own specialist literature. (2) How much translation versus free composition? Volk and others weigh how far Euthymius rendered the Georgian and how far he elaborated it into a fresh Byzantine spiritual novel, and Euthymius’s broader profile as a metaphrast (a reworker, not a literal translator) keeps this live. But both disputes presuppose Euthymius: they concern the manner and degree of his responsibility for the Greek, not a return to the Damascene.5
What it does not touch. This is a question about the Greek text’s author, not about the identification of Josaphat with the Buddha. Whoever penned the Greek, the name still descends from bodhisattva and the plot is still the Buddha’s; fixing Euthymius merely dates and locates the moment the tale became Greek and Christian — c. 980s, on Athos, out of the Georgian — rather than in eighth-century Damascus.
Sound. Euthymius the Athonite, not John of Damascus, stands behind the Greek Barlaam and Ioasaph. The Damascene ascription rests on a later scribal reading of the “John the Monk of St Sabas” heading and was propagated by the martyrologies and older editions; it collapses once the Greek is seen to depend on the Georgian Balavariani, which the eighth-century Damascene could not have used. The positive attribution to Euthymius is triangulated by the textual dependency, the near-contemporary Georgian Life of John and Euthymius that lists the Balahvar romance among his Georgian-to-Greek translations, and the internal Byzantine-Georgian features of the work, and it is the verdict of the standard critical edition (Volk), which files the piece among the Damascene’s spuria. The only surviving debate — whether Euthymius composed or commissioned it, and how much he translated versus recomposed — operates entirely on the Euthymian side of the ledger.
