A Few Words about Saadi
Saadi lived in 13th century, but he’s a man for all centuries. The rich depth of his writings and ideas with social and moral values have gone beyond time. His words have been quoted by Persian speaking people inside Iran and outside alike. Even Western sources have quoted him and continue to do so. He’s  widely recognized as one of the great masters of classical Persian literature. Some even title him second only after Ferdowsy whose position for saving the Persian Language is unparalleled and no one could even do what he did.

The reputation of Saa’i in Persian literature is because of his eloquence in using the language. After 8 centuries, his works are still easy to understand and his ideas are still admirable for the speakers of the language. His style of Farsicizing borrowed words from Arabic in Persian made it a lot easier to use those words in everyday use and understand them although Arabic was not a language of the same origin as Persian.

Saadi was a man of learning. Spending infancy and childhood without a father and going through youth in poverty and hardship never stopped him from pursuing learning. Therefore, he left his birthplace to Baghdad where Nezamieh university was the center of knowledge and many studied there in the Islamic world. Among various subjects that he studied there, he proved to be excellent in Arabic literature, Islamic sciences, history, governance, law and Islamic theology.

Saaadi was a man of traveling. Mongols invasion and unstable situation in Iran led him a lifetime of living abroad in various countries like Anatolia, Syria, Egypt,Iraq, Sindh (Today’s Pakistan), India, Central Asia, Hijaz (Today’s Saudi Arabia), etc. Eventually, after 30 years, he returned to his birthplace as an elderly man and was welcomed and highly respected.

He was titled “Sheikh” because of his knowledge and found followers who pursued his values and words.

Saadi’s Literary Works
Within two years after his return to Shiraz, Saadi wrote his two most famous books: Bustan, also known as Bostan (The Orchard) in 1257 and Golestan, known as Gulistan (The Rose Garden) in 1258. Bostan is entirely in verse introduces moral virtues and Gulistan is mainly in prose containing stories and personal anecdotes.

His works in forms of Lyrics and Odes are also well-known by the enthusiasts of Persia literature. He has created some works in Arabic as well.
One of his most famous works. There are several translations of his works is as below:

بنى‌آدم اعضای یک پیکرند
که در آفرینش ز یک گوهرند
چو عضوى به درد آورَد روزگار
دگر عضوها را نمانَد قرار
تو کز محنت دیگران بی‌غمی
نشاید که نامت نهند آدمی

This translation is by Vahid Dastjerdi:

Adam’s sons are body limbs, to say;
For they’re created of the same clay.
Should one organ be troubled by pain,
Others would suffer severe strain.
Thou, careless of people’s suffering,
Deserve not the name, “human being”.

This one by Iraj Bashiri:

Of One Essence is the Human Race,
Thusly has Creation put the Base.
One Limb impacted is sufficient,
For all Others to feel the Mace.
The Unconcern’d with Others’ Plight,
Are but Brutes with Human Face.

And by Richard Jeffrey Newman:

All men and women are to each other
the limbs of a single body, each of us drawn
from life’s shimmering essence, God’s perfect pearl;
and when this life we share wounds one of us,
all share the hurt as if it were our own.
You, who will not feel another’s pain,
you forfeit the right to be called human.

The Construction & Architecture of the Mausoleum of Saadi
Saadi was buried in a village outside Shiraz which is now part of the city although it’s at the outskirt in a relatively poor neighborhood. Under Karimkhan-e Zand, the 18th century ruler of Shiraz, the present Saadi’s mausoleum was built to further honor him. It’s in form of a multi-sided building with a cupola on top. From outside it may look like a square structure due to its flat facade decorated with Shirazi tiles depicting tree of life in various colors. Inside, you can see the 8 corners of the building and large lamp hanging from the ceiling. His grave is beautifully carved in Persian.

Later this building was connected to another tomb of a Shirazi poet, Shurideh Shirazi by a colonnade portico. Under Reza Shah, the father of the last Shah of Iran and founder of Pahlavi dynasty,  the mausoleum was restored and annexed by some newer parts. Andre Godard, the French architect had been assigned the task of restoring several historical monuments in Iran and so forth.
The Mausoleum of Saadi is located inside a garden where beautiful flowers and several cypress trees are planted to make the setting even more beautiful. A fish pond in an underground reached by some steps lead visitors to some water channels that has been in use since the time of Saadi at this place. Today there’s some fish crossing channels and coming to the center where people can see them.
