《葉珊散文集》為楊牧19歲至25歲間「感情和思想的投影」，東海大學就讀時期，他閱讀了大量英國浪漫主義詩人如華茨華斯（William Wordsworth，1770-1850）、柯律治（Samuel Taylor Coleridge，1772-1834）、拜倫（George Gordon Byron，1788-1824）、雪萊（Percy Bysshe Shelley，1792-1822）、濟慈（John Keats，1795-1821）等人的作品，深受啟發與影響。集中第二輯「給濟慈的信」，為其服役期間所作，即使在戰地水井馬燈中，作家仍反覆思辨浪漫主義的真義，並表現在其創作中，此種實踐畢生不渝，迄於晚期作品。本文意在重新耙梳楊牧對浪漫主義的思考，側重其初期思想的形成與表現分析，並擬由創作源頭梳理，持續觀察楊牧從大度山到西雅圖的創作歷程，希望經由縱時性作品的分析，明其對西方浪漫主義的執著與踐履，並進一步聯繫現代中國接受浪漫主義一代的特殊情境與創作特質，從而指出楊牧對此脈絡的承繼、發揚與意義。

Ye Shan’s Prose Collection is the “projection of feelings and thoughts” of Yang Mu between the ages of 19 and 25.

Even in the battlefield of Kinmen accompanied with wells and barn lanterns, Yang had never given up on exploring the true meaning of romanticism and he further embodied this thinking into his writing. This spirit persisted throughout his life and still could be seen in his late works.
