The greatness of Sunthorn Phu lies not so much in correct and ornate style, which is the aim of most Thai poets, as in the very simplicity and sincerity of his expression. Unlike so many other poets, he wrote from his heart and not from his head. Not being a learned man, he confined himself to simple forms of verse and simple language. But in his own field, in what we call Glon poetry, he was past master and his works are unsurpassed and probably can never be surpassed, although no other Thai poet has had so many imitators. But Sunthorn Phu reigns supreme, because in all his poetry, in Phra Abhai Mani, in his Nirats with their mixture of romance, pathos and humour, he touched the heartstrings of the common people. That is why he is so deservedly called the People's Poet.
