Garden creators need inspiration, and it should come as no surprise that often the inspiration comes from religious or philosophical traditions, and this may be at the root of Eve Pollard's observations that she is philosophically challenged by her garden, for I suspect that she is in an ongoing philosophical dialogue with it.
The word paradise comes from a Persian word for garden, and at the root of this usage is the idea that the garden is a recreation of the ideal world, a taste we hope of things to come in the eschatological future.
There is a rich variety of Gardens inspired by Christian teachings. There are Marian Gardens devoted to the honour of Mary the mother of Jesus; we have the paradise gardens of monasteries, which were near the churches and which were intended to give glory to God and a taste of paradise to come after death. To some extent the word philosopher is less apt in the cases of Christian gardens than is the word theologian, for Christian thought is Theology, a discipline that uses philosophy, but is not reducible to it
Christian gardens are inspired by a combination of factors. If you look at the image of a monastery garden below you will see that it combines appearance with utility.You see that it is well laid out in a pattern pleasing to the eye, and there are some beautiful red flowers that seem to be roses in the background. But the garden is essentially useful, for it grows vegetables for the monastery and in the past grew healing herbs, though nowadays modern medicine is used instead. Flowers may be grown to adorn the monastery church, for Catholicism places great store by the involvement of the senses in the collective, formal act of worship that we call the liturgy[mass.]
Yet there are other spiritual resources. Take the example of Mary Reynolds, whose book The Garden Awakening is shown below. She draws upon the ancient traditions of her native Ireland to inspire her professional garden designs, and she seems to be a pagan of some kind, though she does not say which. Her book is well written and is worth reading, for the enchanting character she that she seems to be and for the clear advice on garden design that she gives.
Each religion has its own style of garden.Muslim gardens are devoid of statuary as the religion rejects images of humans, but in keeping with the Islamic view that the world is ordered and organized by God they are intricately designed and often contain flowing water, an element whose importance is clear in the hot lands from which Islam sprang. Below you will see an example of a Muslim garden, which emphasizes and pattern in keeping with Islam's precepts.
