我看了一下英文維基百科（中文跟日文的維基都資料不多）https://en.wikipedia.org/wiki/Romanos_IV_Diogenes關於贖金的部分有一段：【At first Alp Arslan suggested a ransom of 10,000,000 nomismata to Romanos IV, but he later reduced it to 1,500,000 nomismata, with a further 360,000 nomismata annually.[24]】這邊是說阿爾普提出100萬，後來又提高到150萬+每年36萬。島嶼人在本文所提到的「凱撒同意，每日向蘇丹的內庫進貢一千第納爾」，以一年約360天來算也是36萬沒錯而有關失去皇位後的那段故事，在英文維基百科也有提及：【Before leaving the fortress, he collected all the money he could lay his hands on and sent it to the Sultan as proof of his good faith, along with a message: "As emperor, I promised you a ransom of a million and a half. Dethroned, and about to become dependent upon others, I send you all I possess as proof of my gratitude".[47]】[24]：Finlay 1854, p. 42[47]：Finlay 1854, p. 44這兩段是同一個出處，看了一下條目中的參考文獻那邊是這個Finlay, George (1854), History of the Byzantine and Greek Empires from 1057 to 1453, vol. 2, William Blackwood & Sons
