Greco-Buddhism too [0]. There is also a hypothesis that the strengthening of the Silk Road from those conquests led to Indian representatives being sent to the West which "may have helped prepare for the ethics of Christ" [1].
> Buddhist gravestones from the Ptolemaic period have been found in Alexandria in Egypt decorated with depictions of the dharma wheel, showing that Buddhists were living in Hellenistic Egypt at the time Christianity began.[16] The presence of Buddhists in Alexandria has led one author to note: "It was later in this very place that some of the most active centers of Christianity were established."[14] Nevertheless, modern Christian scholars generally hold that there is no direct evidence of any influence of Buddhism on Christianity, and several scholarly theological works do not support these suggestions.[17][18] However, some historians such as Jerry H. Bentley suggest that there is a real possibility that Buddhism influenced the early development of Christianity.[19]
> It is known that prominent early Christians were aware of Buddha and some Buddhist stories. Saint Jerome (4th century CE) mentions the birth of the Buddha, who he says "was born from the side of a virgin"; it has been suggested that this virgin birth legend of Buddhism influenced Christianity.[20] The early church father Clement of Alexandria (died 215 AD) was also aware of Buddha, writing in his Stromata (Bk I, Ch XV): "The Indian gymnosophists are also in the number, and the other barbarian philosophers. And of these there are two classes, some of them called Sarmanæ and others Brahmins. And those of the Sarmanæ who are called 'Hylobii' neither inhabit cities, nor have roofs over them, but are clothed in the bark of trees, feed on nuts, and drink water in their hands. Like those called Encratites in the present day, they know not marriage nor begetting of children. Some, too, of the Indians obey the precepts of Buddha (Βούττα) whom, on account of his extraordinary sanctity, they have raised to divine honours."[21]
