In his history of the Order of St. John, the 18th-century historian Abbe Vertot (whose history is largely based on - but often confuses - the earlier one of Giacomo Bosio) indicates that La Valette was indeed the same age as both Suleiman I and Lala Kara Mustafa Pasha (the commander of the Ottoman land forces), which would mean that he was actually 70 years old at the time of the siege.
