Olga Kubica sets out to dismantle a category, and on that front she succeeds. Her thesis is that, for all the traffic between Greeks and Buddhists in Bactria and Northwest India from Alexander to the turn of the era, the phenomenon we call "Greco-Buddhism" "never truly occurred" (publisher's description). What the sources record is accommodation on a "middle ground" (after Richard White), not a fusion of doctrine. The negative half of this is welcome and overdue. The compound has long carried more freight than the evidence can bear, and Kubica is right that syncretism, strictly the reconciliation of belief-systems, is not what the Kandahar edicts or the Bajaur reliquaries show (4). She is careful, too, to allow partial syncretisms while rejecting the totalising label (4).

The trouble is a slide that governs the book: from the defensible claim that "Greco-Buddhism" is a problematic category to the far stronger conclusion that there is no such phenomenon as Greco-Buddhism (214). The first is about the scholarly suitability of a term; the second is about history, and a negative thesis of that magnitude needs positive evidence of absence, not merely the absence of evidence. The formula that carries the conclusion - the Greeks "did not convert to Buddhism but to what they thought Buddhism was" (215) - sounds like a refutation, but it holds true of every conversion in history and so does no work specific to this case. And the concession in the same paragraph gives the game away: "even if there were cases of genuine conversion of the Greeks to Buddhism in this early period, what cannot be ruled out, since the sources we have are very scarce, still they should be considered in the context of the so-called middle ground" (215). While genuine conversion cannot be ruled out, the reader is merely asked to file it under the preferred rubric. That is the negative thesis being withdrawn just where it is under most pressure.

The theoretical apparatus was built for other worlds. White's "middle ground" was developed for the colonial Great Lakes, a setting defined by rough balance of power and a documented record of councils. Transplanted to Bactria, at least two of its conditions fail: the Indo-Greeks were the ruling military elite, not a party in equipoise, and the dense diplomatic record is simply absent, leaving fragmentary inscriptions, coins and one dialogue of contested date. Kubica notes the comparison but does not stress-test it. Worse, when White's Algonquian case is imported the roles invert. There the subordinated party accommodates an imposed religion, whereas in Bactria the Greeks were the rulers encountering Buddhism as the religion of subjects. Hence, structurally it is the saṅgha, not the Greek elite, that occupies the Algonquian position. De Certeau fares no better: to assign "strategies" to Greeks and "tactics" to Buddhists forgets that the Mauryan saṅgha had institutions and royal patronage, and that Aśoka deployed dhamma as imperial soft power across his diverse populations that included a sizable Greek community. The selective application reproduces the very Hellenocentrism the book means to dismantle - as does the fact that its categories come wholly from (western) modern social theory (White, de Certeau, Nora, Barth, Bhabha, Kraidy), never from the Buddhist traditions whose encounter it studies. The same double standard governs diffusionism. Kroeber is quarantined for his German-nationalist neighbours (Kossinna, 4-5), yet Strzygowski's "Greek Iranism in Buddhist sculpture" is endorsed much later (176), though his völkisch, anti-classical commitments are far better documented.

The theoretical framework has a real weakness, though not the obvious one. Kubica treats the individual encounters of Pyrrho, Calanus, Menander, and Nāgasena. On Pyrrho she meets the question directly: she cites Beckwith and Kuzminski, quotes the Aristocles passage (Eusebius 14.18.1-5), and grants the parallels of ataraxia-nibbāna and pragmata-dhammas, conceding the influence theory is "not at all unfounded." Then she withdraws it, on two grounds: that it falls earlier than her post-Alexander focus, and that it's philosophical rather than social, "omitted here," as she puts it (35). That bracketing is where the argument is weakest. Her remit runs from the "conquest of these areas by Alexander the Great" (1), yet Pyrrho travelled with Alexander and the gymnosophists were met in the course of the conquest itself, so by her own terminus they fall inside the time frame, not before it. The exclusion is not only chronological but methodological: contact and influence are processes, not datable instants. She treats a diachronic encounter synchronically, fixing a window and cutting the encounter off by reclassifying it as "philosophical." The negative thesis survives not because the evidence was met, but because it was defined out of the field. What is truly absent is narrower - my Yavanayāna reading of that same passage is not cited (Halkias 2020) - but an encounter acknowledged and then set apart is not thereby answered.

Nor can the frame quite contain its own chronological choices. Kubica stops at c. 10 CE and at the Hindu Kush, and she records the self-immolation topos of Calanus and Zarmanochegas herself (32-33, 209). But she keeps Calanus a gymnosophist and does not meet the argument (Halkias 2015) that his self-immolation marks him probably a Buddhist. And the traffic runs further than the book allows, along a line drawn from her own materials. Aśoka's Thirteenth Rock Edict aims its victory by dhamma at five Hellenistic kings, Ptolemy II Philadelphus among them (52-53), and it was Ptolemy II who founded, and named for his mother, the Red Sea port of Berenike. There, centuries on, excavators found a Gandhāran-style Buddha of Aegean marble in the Isis temple, early second century CE, with a bilingual Greek-Sanskrit dedication by the kṣatriya Vāsula (Greek "Vazulas") dated to 248 CE under Philip the Arab. Its Sanskrit the only such text to name a Roman emperor (Sidebotham et al. 2025). Clement of Alexandria, further west still, already knew "Boutta" honoured as a god (Stromateis 1.15). The edict Kubica herself edits and the Buddha unearthed at its addressee's harbour mark two ends of a trajectory her frame opens but, halting at c. 10 CE, does not follow. None of this revives the maximalist synthesis (a genuine fusion of Greek and Buddhist doctrine) she is right to retire, but it shows the phenomenon mobile and materially attested, and makes the argument from silence harder to sustain. The more so, as the archaeology moves against her floor in her own pages, where she reports the Barikot trench (BKG 16), possibly of Indo-Greek date, and concedes it "can revolutionize our thinking" (216-217).

In all fairness, her criticisms of my 2014 article largely land. The appeal to Kroeber's stimulus diffusion was under-theorised, and the closing phrase "the first Europeans ever to be converted to Buddhism" sits ill with that essay's own argument. I would call it a rhetorical lapse rather than a considered colonial claim; but a lapse it was, and one I have since tried to correct. The verdict is a division of labour. Kubica gives the better method. The tradition she argues with gives the better questions. Her book is disciplined, philologically careful and necessary, and should be read by anyone in the field. But it is by no means the last word on whether the encounter occurred; it is, rather, the most rigorous account of why "Greco-Buddhism" was always the wrong label for the question. One wish for a bolder book remains: the Sarvāstivāda Abhidharma that dominated the Northwest, which she touches by way of Bronkhorst and Frauwallner (36), could have carried far more weight in a study of what Buddhism did and did not absorb. The book we still lack is the one written diachronically and from the Buddhist side. Until it arrives, both Kubica and her interlocutors are circling a centre that remains unexamined. Which is, in itself, no small thing to have made visible.
