— Rembrandt pintor neerlandés del siglo XVII 1606 - 1669
Original (versión en inglés): I am most astonished by what has been written about the [painting] 'Alexander', which is so well done that I must suppose there are not many lovers of art [amatori] at Messina. I am also surprised that Your Lordship [Don Antonio Ruffo] should complain as much about the price as about the canvas, but if Your Lordship wishes to return it as he did the sketch [schizzo] of Homer, I will do another Alexander... If Your Lordship likes the Alexander as is, very well. If he does not want to keep it, six hundred florins remain outstanding. And for the Homer [painting] five hundred florins plus the expenses of canvas, it being understood that everything is at Your Lordship's expense. Having agreed to it, would he kindly send me his desired measurements. Awaiting the response to settle the matter.
