Editing Theatrum Orbis Terrarum (section)

==Editions==
After the initial publication of {{Lang|la|Theatrum Orbis Terrarum}}, Ortelius regularly revised and expanded the atlas,<ref name=WDL1/> reissuing it in various formats until his death in 1598. From its original seventy maps and eighty-seven bibliographic references in the first edition (1570), the atlas grew through its thirty-one editions to encompass 183 references and 167 maps in 1612.

The legends of most maps name the author whose map Ortelius adapted. In the preface Ortelius credits [[Frans Hogenberg|Franciscus Hogenberg]] with engraving nearly all the maps.<ref>{{cite book | title = Theatrum orbis terrarum | author = Ortelius, Abraham | publisher = Antuerpiae: Auctoris aere & cura impressum, absolutumq́ue apud Aegid.

The 1573 ''Additamentum'' to the atlas is notable for containing [[Humphrey Llwyd]]'s ''[[Cambriae Typus]]'', the first map to show Wales on its own.<ref name="Map of Wales">{{cite web | url=http://www.gtj.org.uk/en/small/item/20019/ | title=Map of Wales, 'Cambriae Typus' by Humphrey Lhuyd, 1573 | work=Gathering the Jewels | access-date=18 May 2011}}</ref>

{{Lang|la|Theatrum Orbis Terrarum}} is used as the centerpiece of the [[Fool's Cap Map of the World]], which is a satirical presentation of Europe's understanding of the globe.<ref>{{Cite web |last=Young |first=Lauren |date=2017-02-13 |title=The Enduring Mystery of the 'Fool's Cap Map of the World' |url=http://www.atlasobscura.com/articles/16th-century-fools-map |access-date=2024-04-18 |website=Atlas Obscura |language=en}}</ref>

From the 1630s, the [[Willem Blaeu|Blaeu]] family issued their work under a similar title, ''[[Atlas Maior|Theatrum orbis terrarum, sive, Atlas Novus]]''.
