This book brings together in English translation for the first time the two editions of Sir Syed Ahmed Khan's classic account of the monuments and environs of the pre-colonial city of Delhi, titled in Urdu Asar-us-Sanadid (The Remnants of Ancient Heroes). The translator provides a commentary in the form of annotations and appendices that demonstrates the historical development of the text between 1847 and 1854, also reflecting the life of its subject, Delhi, which was to be irreversibly transformed by the cataclysmic events of 1857. The volume includes sketches based on the lithographs in the first Urdu edition. The translation fills a crucial lacuna in the historical archive for nineteenth-century Delhi and will be a valuable resource for urban historians and students of Delhi's monumental history.
