Lake Mainit in Ancient Maps

I wrote in 2005 about the 1734 map of the Jesuit Priest Fray Murillo Vellarde reflecting the name Lake Mainit (here: http://pidjanga.blogspot.com/2005/08/pueblo-de-mainit-1749.html). 

Now, I met the actual map face to face... here... in our office building in Quezon City! 

February 20 to 24, 2016 at PSSC Building, Quezon City: A Cartographic Exhibit based on the research of Supreme Court Senior Associate Justice ANTONIO CARPIO - Historical Truths and Lies, Scarborough Shoal in Ancient Maps. 

1600s - Lake is reflected in the maps as a dent probably mistaking it as part of the ocean. All maps in display have no inland lake, hence no name assigned. Understandably because these maps were purely for ocean navigation and reports of routes identified.

1700s - Suprisingly referred to as SAPONGAN in most maps. My theory points to Jabonga being mispelled sa Saponga by french cartographers. The lake in these maps are now clearly an inland lake. I take notice of the names of other places as well "Higaquet", "Siarigao", etc.

1800s - Amazing to see that most the maps in this era do not reflect a lake. In the latter part, it eventually named our lake - LAKE MAINIT.
